视频镜头边缘检测方法
基本思想：对比相邻帧间的特征 认为有重大变化的地方是镜头边缘的发生之处
Although cut detection appears to be a simple task for a human being, it is a non-trivial task for computers. Cut detection would be a trivial problem if each frame of a video was enriched with additional information about when and by which camera it was taken.
如果相邻图像帧之间的特征发生了明显变化，则认为发 生了镜头变化，需要对视频进行切分

镜头分类示例
长镜头(LS)：显示场景的全貌 中镜头(MS)：表现人物的动作，如谈话等 短镜头(CU) ：近距离刻画人物的表情
长镜头 中镜头 短镜头
注：一般在电影中镜头常被分为7类，即特长(XLS)、长(LS)、中长(MLS)、 中(MS)、中短(MCU)、短(CU)和特短(XCU)，

压缩域差法
不对图像解压，而是直接用JPEG压缩图 像帧的DCT系数作为帧相似度衡量的标准 。 省去解压步骤，直接从原始视频数据流 中提取特征，从而加快检测速度。 每个压缩域系数保留了原始图像帧中或 图像帧间最重要特征，所以压缩域系数 可以有效分析视频数据。

矩不变量法
图像矩不变量具有比例、旋转和过渡不变 性的特点，可以用来进行镜头边缘检测。 图像 f(x,y) 的矩定义为:
纹理物体缺陷的视觉检测算法研究--优秀毕业论文
摘 要
在竞争激烈的工业自动化生产过程中，机器视觉对产品质量的把关起着举足 轻重的作用，机器视觉在缺陷检测技术方面的应用也逐渐普遍起来。与常规的检 测技术相比，自动化的视觉检测系统更加经济、快捷、高效与 安全。纹理物体在 工业生产中广泛存在，像用于半导体装配和封装底板和发光二极管，现代 化电子 系统中的印制电路板，以及纺织行业中的布匹和织物等都可认为是含有纹理特征 的物体。本论文主要致力于纹理物体的缺陷检测技术研究，为纹理物体的自动化 检测提供高效而可靠的检测算法。 纹理是描述图像内容的重要特征，纹理分析也已经被成功的应用与纹理分割 和纹理分类当中。本研究提出了一种基于纹理分析技术和参考比较方式的缺陷检 测算法。这种算法能容忍物体变形引起的图像配准误差，对纹理的影响也具有鲁 棒性。本算法旨在为检测出的缺陷区域提供丰富而重要的物理意义，如缺陷区域 的大小、形状、亮度对比度及空间分布等。同时，在参考图像可行的情况下，本 算法可用于同质纹理物体和非同质纹理物体的检测，对非纹理物体 的检测也可取 得不错的效果。 在整个检测过程中，我们采用了可调控金字塔的纹理分析和重构技术。与传 统的小波纹理分析技术不同，我们在小波域中加入处理物体变形和纹理影响的容 忍度控制算法，来实现容忍物体变形和对纹理影响鲁棒的目的。最后可调控金字 塔的重构保证了缺陷区域物理意义恢复的准确性。实验阶段，我们检测了一系列 具有实际应用价值的图像。实验结果表明 本文提出的纹理物体缺陷检测算法具有 高效性和易于实现性。 关键字: 缺陷检测；纹理；物体变形；可调控金字塔；重构

影视剧的各种剪辑技巧英文
影视剧的各种剪辑技巧英文Here are some various editing techniques used in film and television:1. Cut: A basic editing technique that involves transitioning from one shot to another, creating a seamless flow between scenes.2. Cross-cut: Also known as parallel editing, this technique involves alternating between two or more different storylines happening simultaneously.3. Match cut: A cut that links two shots, often by matching the action or composition, to create a smooth transition.4. Jump cut: A cut that abruptly transitions within the same shot to createa disorienting or dramatic effect.5. Montage: A sequence of shots or images edited together to condense time or convey a series of events or emotions.6. Split screen: Dividing the screen into two or more sections to show multiple images or perspectives simultaneously.7. Flashback/flashforward: An editing technique that transports the viewer to an earlier or future time to provide important context or foreshadowing.8. Dissolve: An edit that gradually fades out one image while fading in another, creating a blending effect between the two shots.9. Wipe: A transition effect where one shot replaces another by sliding, flipping, or pushing the previous shot off-screen.10. Slow motion: Reducing the playback speed of a shot to create a dramatic or stylized effect.11. Fast motion: Accelerating the playback speed to create a comical or energetic effect.12. Freeze frame: Pausing a shot to create a still image, often used for dramatic emphasis or to highlight a specific moment.13. Crossfade: Gradually blending the audio from one shot into the next during a transition.14. Sound bridge: Overlapping the audio from one scene into the next scene to create a smooth audio transition.15. Foley: Adding or enhancing sound effects in post-production to create a more realistic or immersive audio experience.These are just a few examples of editing techniques. There are many more techniques used in film and television to enhance storytelling and create an engaging viewing experience.。

iDS-2CD7A46G0-IZHS(Y)(R)4 MP IR Varifocal Bullet Network Camera⏹High quality imaging with 4 MP resolution⏹Excellent low-light performance via DarkFighter technology⏹Clear imaging against strong back light due to 140 dB WDRtechnology⏹Efficient H.265+ compression technology to savebandwidth and storage⏹Advanced streaming technology that enables smooth liveview and data self-correcting in poor network⏹ 5 streams and up to 5 custom streams to meet a widevariety of applications⏹Water and dust resistant (IP67) and vandal proof (IK10)FunctionFace CountingWith the embedded deep learning algorithms, the camera integrates multiple intelligences. It counts persons and samples the face features simultaneously, and compares them with the built-in face library, so to remove the duplicated person. It counts persons and reports a face alarm simultaneously to achieve both the entrance control and people counting.Hard Hat DetectionWith the embedded deep learning algorithms, the camera detects the persons in the specified region. It detects whether the person is wearing a hard hat, and captures the head of the person and reports an alarm if not.Multi-Target-Type DetectionWith the embedded deep learning algorithms, the camera detects and captures the face and human body in the specified region and outputs the features, such as gender, age and top color. It supports a structurized modeling of the face and human body to achieve a structurized data collection.Queue ManagementWith embedded deep learning based algorithms, the camera detects queuing-up people number and waiting time of each person. The body feature detection algorithm helps filter out wrong targets and increase the accuracy of detection. MetadataMetadata uses individual instances of application data or the data content. Metadata can be used for third-party application development.Smooth StreamingSmooth streaming offers solutions to improve the video quality in different network conditions. For example, in poor network conditions, adapting to the detected real-time network condition, streaming bit rate and resolution are automatically adjusted to avoid mosaic and lower latency in live view; in multiplayer network conditions, the camera transmits the redundant data for the self-error correcting in back-end device, so that to solve the mosaic problem because of the packet loss and error rate.SpecificationCameraImage Sensor 1/1.8″ Progressive Scan CMOSMin.

With respect to the contracted image, an inter-frame difference unit determines the inter-frame difference D.sub.n between the input and reference images and the temporal change &Dgr;D.sub.n in the inter- frame difference. A first judging unit judges, according to the above data, the input frame to be a non-cut frame, a cut frame or a cut frame candidate. When the input frame is judged to be a cut frame, an output unit effects a cut frame output, and then the next input frame processing is performed. With respect to a cut frame candidate, a chrominance histogram correlation unit calculates the correlation &rgr; of the color distribution of the chrominance histogram by using contracted image of chrominance signal. A second judging unit makes an overall judgment on the inter-frame difference D.sub.n, temporal change &Dgr;D.sub.n therein, and correlation &rgr; for the cut frame detection.申请人：KOKUSAI DENSHIN DENWA KABUSHIKI KAISHA代理机构：Westman, Champlin & Kelly, P更多信息请下载全文后查看。

基于深度学习的海上目标一维序列信号目标检测方法
Vol. 36 No. 12Dve. 2020第36卷第12期2020年12月信号处理Journal of Signal Processing文章编号：1003-0530(2020)12-1987-11基于深度学习的海上目标一维序列信号目标检测方法苏宁远陈小龙关键黄勇刘宁波(海军航空大学，山东烟台264001)摘要：当前海面目标检测方法多基于统计理论，检测性能受背景统计特性假设的影响，本文从信号预测和特征分类两个角度，分别采用长短时记忆网络# LSTM )和卷积神经网络(CNN )对信号时间序列幅度信息进行处理，用 于海上目标一维序列雷达信号检测，该方法不需事先假设背景统计特性，泛化能力更强。
基于LSTM 序列预测的目标检测方法通过用海杂波信号幅度时间序列对网络进行训练，再用训练后的网络对后续序列进行预测，并与后续实测信号进行比较，实现目标检测。
基于CNN 序列分类的目标检测方法中采用截取的海杂波信号和目标信 号幅度序列作为数据集样本，对一维卷积核CNN 进行训练，使其具有识别目标杂波信号特征能力，从而实现目 标检测。
最后，采用IPIX 和CSIR 实测海杂波数据对两种方法进行验证，结果表明两种方法均可实现一维序列 信号中海面目标的检测，但LSTM 预测方法对于长序列检测的实时性有待于进一步提高；CNN 分类方法可实现实时检测，但仅利用信号幅度信息，检测性能仍需进一步提升。

蜗管呈盘旋的"蚊香状"清晰可见,前后半规管汇于总骨脚,球囊(saccule,S)呈高信号近似为圆球形,长短径约为1.2mm×0.9mm.椭圆囊(utricle,U)信号稍高,呈圆弧管状形,长短径约为4.5mm×1.1mm;椭圆囊与球囊之间有明显的较低信号分界,此低信号为骨性结构的前庭嵴(vestibularcrest,VC).前后轴一135.MPVR图上,前后半规管,总骨脚显示最佳,外(水平)半规管与椭圆囊重叠,耳蜗管显示清楚(图4).在上下轴一45.左耳内听道横截面(0.7mm)MPVR图上,可以同时清晰地显示4根神经分支(图5):1前庭上神经(nervi vestibularissuperior,NVS);2前庭下神经(nervivestibularisin-

TElOOms)对内耳进行高分辨成像,结果表明该序列明显较少受到磁化敏感伪影的影响.Christian等报道在内耳和桥小脑角的MR成像中,采用3D序列比2D序列能提供更多的细节,以便更准确地观察精细解剖结构和更多地发现病变.本组资料把3D序列的TE提高到800ms以上,与常规T.比较更能提高液体与骨的信号强度对比,在显示内耳的骨螺旋板,前庭阶,鼓阶,椭圆囊,球囊,前庭嵴和内听道四神经分支的精细结构方面明显优于常规T(P<0.01).本组资料表明,应用MR水成像技术能清晰显示内耳迷路及内听道四神经分支的精细结构和解剖关系,其图像立体直观,具有其他影像学方法不可替代的作用.笔者对迷路及内听道主要结构进行了观察与测量,其中3个半规管形态近似,呈296放射学实践2003年4月第18鲞堑塑!!竺!:垒1:!!:

2. SPATIO-TEMPORAL METRICS FOR DYNAMIC CHANGE DETECTION
A sequence of images may be characterized by some spatial and temporal information content. Spatial information represents the change in an individual frame, while temporal information characterizes inter-frame changes. Histogram feature is a typically used technique for spatial information'0'2 in color images. Edge-based technique is also widely used in spatial feature extraction.11'5 In this work, we use Sobel edge operator to exatract the spatial information. Let us consider an image frame k, f(i, j, k) having a total of P pixels. Let s(i, j, k) represent the Sobel edgeoperated spatial information of the frame. A metric representing spatial information content (SIC) is then given
-
Temporal information content (TIC) is then given by,
TIC(k) =
t2(i,j,k) T2
(3)
Here T s the mean value of temporal information of k-th frame. As mentioned earlier, a single metric called velocital information content (VIC) which incorporates both the spatial and temporal content is found to be a better representative of change detection in image sequence.
Keywords: Spatio-temporal metric, multiresolutional feature, scene-cut, image sequence
:1. INTRODUCTION
Processing of large databases of image and video sequences is becoming increasingly more challenging with the rapid growth of multimedia applications. Efficient storage and retrieval techniques necessitate the smart detection of dynamic changes in an image sequence, which may be used to form an index database. A video sequence usually consists of many scenes. Each scene is a combination of some frames that has continuous spatio-temporal property. A scene change is usually associated with the dynamic changes in image content, motion, and audio information among the frames. The change could be abrupt or gradual. Dissolve, fade in/out, and wiping are examples of gradual change, while scene-cut is an example of abrupt change. Scene-cut detection, often is therefore related to video segmentation, which is usually the first task in any video processing. Segmentation techniques primarily, use some metrics based upon the changes in image statistics, motion, and audio information. Significant research has been done in these three paradigms resulting in many different techniques such as model-based,' histogram-based,2 pixel-based,3 motion-based,4 and feature-based comparison.5'6 All these methods make use of some spatial and temporal metrics. The paper by Boreczky et. al.7 compares different techniques for video shot boundary detection. Recently, a single metric called velocital information content (VIC) has been found8'9 to be very effective in charting image artifacts in digital image sequences. The work presented in this paper extends this metric in the determination of dynamic changes in an image sequence. A second motivation to this work is the use of multiresolutional analysis of this metric. In this research report, the application of a modified VIC at different resolutional levels is presented. Wavelet decomposion of image sequences is used here for the multiresolutional analysis. This paper is organized as follows: an introduction to spatio-temporal feature metrics, multiresolutional analysis of metrics, simulation results with emphasis on fusion, and finally comparison of different metrics.

ABSTRACT
This paper proposes to use a multiresolutional spatio-temporal metric for the segmentation of an image sequence. In particular, scene-cut detection performance from an image sequence will be furnished. Wavelet decomposition is used for the multiresolutional analysis. The segmentation results obtained here can be used in the video browsing and indexing in multimedia applications.
Here is the mean value of spatial information of k-th frame over the total pixels. Temporal information, on the other hand, is obtained from the frame differencing as given below. With backward difference, (2) t(i, j, Ic) = f(i, j, k) f(i, j, k - 1)
