Abstract: This paper discusses a novel fast approach for moving object detection in H.264/AVC compressed domain for video surveillance applications. The proposed algorithm initially segments out edges from regions with motion at macroblock level by utilizing the gradient of quantization parameter over 2D-image space.
27 Jan 2020 The YOLO object detector is often cited as being one of the fastest deep Video files typically apply some level of compression to reduce the

A tarball is a type of compressed folder, like a zip file, commonly used ROI Segmentation from Brain MR Images with a Fast Multi-Level Spotting of Keyword Directly in Run-length Compressed Documents -- Chapter 34. image partitioning, egocentric object detection and video shot boundary detection. Performance of Adaptive Fast Multipole Methods In Three Dimensions For Video Recommendation Based on Object Detection .
Several Foreground detection techniques and edge detectors have been developed till now but the problem is that it is very difficult to obtain an optimal foreground due to the interference from the factors like weather, light, shadow and clutter.

However, they require an offline training stage and therefore cannot be applied to unknown objects. 2.1 Detection In recently years, Many methods have been developed for moving object de-tection in H.264/AVC bitstream domain. Object detection in still images has drawn a lot of attention over past few years, and with the advent of Deep Learning impressive performances have been achieved with numerous industrial applications.

To our best knowledge, the MMNet is the first work that investigates a deep convolutional detector on compressed videos. Our method is evaluated on the large-scale ImageNet VID dataset, and the results show that it is 3x times faster than single image detector R-FCN and 10x times faster than high-performance detector MANet at a minor accuracy loss.

Fast Object Detection in Compressed Video Abstract: Object detection in videos has drawn increasing attention since it is more practical in real scenarios. Most of the deep learning methods use CNNs to process each decoded frame in a video stream individually.

object motion becomes large, color contrast becomes low, image noise soars to an unacceptable level, etc. In addition, the computational complexity is required to be kept minimum for real-time performance. This paper is organized as follows in the section I. introduction to object detection in video surveillance and in the section II.
