چکیده

Automatic segmentation of foreground from background in video sequences has attracted lots of attention in computer vision. Two different implementations have been completed during the summer. The first one is known as “background subtraction”. The foreground is segmented from the background by directly subtracting a mean background image B from each frame, and retaining those parts of the frame that differ the most from B.

Robust background estimation for complex video sequences

Knowing the background image of a video scene simplifies the general video-object segmentation problem and therefore it is required by several automatic segmentation algorithms. This paper presents a new background estimation algorithm which is applicable to complex video sequences where many objects are simultaneously visible and the background is visible for a short time period only. The algo...

Denoising of Surveillance Video Using Adaptive Gaussian Mixture Model Based Segmentation Towards Effective Video Parameters Measurement

In recent times, capturization of video became more feasible with the advanced technologies in camera. Those videos get easily contaminated by noise due to the characteristics of image sensors. Surveillance sequences not only have static scenes but also dynamic scenes. Many efforts have been taken to reduce video noise. Averaging the frame as an image had limited denoising effect and resulted i...

Smooth Foreground-Background Segmentation for Video Processing

We propose an efficient way to account for spatial smoothness in foreground-background segmentation of video sequences. Most statistical background modeling techniques regard the pixels in an image as independent and disregard the fundamental concept of smoothness. In contrast, we model smoothness of the foreground and background with a Markov random field, in such a way that it can be globally...

A Robust Regression Approach for Background/Foreground Segmentation

Background/foreground segmentation has a lot of applications in image and video processing. In this paper, a segmentation algorithm is proposed which is mainly designed for text and line extraction in screen content. The proposed method makes use of the fact that the background in each block is usually smoothly varying and can be modeled well by a linear combination of a few smoothly varying ba...

Background initialization and foreground segmentation for bootstrapping video sequences

In this study, an effective background initialization and foreground segmentation approach for bootstrapping video sequences is proposed. First, a modified block representation approach is used to classify each block of the current video frame into one of four categories, namely, “background,” “still object,” “illumination change,” and “moving object.” Then, a new background updating scheme is ...
