This paper proposes and investigates fast variable block-size motion estimation algorithms based on merge and split procedures for H.264/MPEG-4 AVC video encoding. The algorithms take advantage of the correlation of the Motion Vectors (MVs) of the d
This application report describes how to build a motion JPEG demo running on Texas Instruments DM6446 processor leveraging the JPEG codec combo and XDC tools provided with the DM6446 DVEVM/DVSDK package. The demo is derived from the motion JPEG demo
In this paper, WP, present a new motion estimation algorithm which determines an initial motion vector and a search window adaptively in video codecs which code and transmit data in a block scan order. The proposed method is based on the motion info
Abstract— We present a novel method for motion segmentation and depth ordering from a video sequence in general motion. We first compute motion segmentation based on differential properties of the spatio-temporal domain, and scale-space inte- gration
Abstract Recently, multiple research groups proposed the concept of direct manipulation, which makes the task of navigation in videos directly related to content of the video. However, the developed systems are still too slow for a broad application
Abstract Estimating relative camera motion from two views is a classical problem in computer vision. The minimal case for such problem is the so-called five-point-problem, for which the state-of-the-art solution is Nist´er’s algorithm [9]. However,
Mutual Information (MI) has been extensively used as a similarity measure in image registration and motion esti- mation, and it is particularly robust for 3D multimodal medical image registration. However, MI estimators are known i) to have a high v
Cooperative Fusion of Stereo and Motion This paper presents a new matching algorithm based on cooperative fusion of stereo and motion cues. In this algorithm, stereo disparity and image flow values are recovered from two successive pairs of stereo i
In this paper, we show a new method to reconstruct and update the background. This approach is based on double-background. We use the statistical information of the pixel intensity to construct a background that represents the status during a long t
Most video surveillance systems require to manually set a motion detection sensitivity level to generate motion alarms. The performance of motion detection algorithms, embedded in closed circuit television (CCTV) camera and digital video recorder (D
In this paper, a fast integer pixel variable block ME algorithm based on JVT which accepted UMHexagonS algorithm is presented for H.264/AVC encoder. With special considerations on the motion activity of the current macro-block, several adaptive sear
This paper presents new approaches in character- izing and segmenting the content of video. These approaches are developed based upon the pattern analysis of spatio-temporal slices. While traditional approaches to motion sequence analysis tend to fo
