    Abstract: The present invention provides a method for processing videos captured through a stereo camera, the videos having a plurality of frames, each frames includes at least a left and a right images. The method includes acquiring videos captured by the pair of stereo cameras (101) and acceleration information of the stereo camera (101) detected through the accelerometer (102); extracting feature points in the right and left images of a current frame; matching the feature points between the right and left images, wherein disparity value of each feature point is computed; clustering the feature points on a current frame into one or more clouds based on their appearance and distance; determining a correspondence between the clouds of the current frame and previous frame; classifying the clouds through estimating statistical disparity distribution of each cloud to identify if the respective clouds are new clouds, existing clouds or unknown clouds; and merging the clouds that are determined to be a same object based on the tracking information and changes of disparity of the clouds over time. A system carrying out the above method is also provided herein.

    Abstract: The present invention relates to a novel method for producing a background model based on the images acquired from a non-static camera. Rule-based statistical multiple image analytical method to process multiple non-overlapping background region of a scene using predetermined threshold values to identify the preferred intensity variance for modeling the background pixel. One of the advantages of the a method for modeling dynamic scene using region-based adaptive statistical learning to model dynamic background within one camera view and scene-based modeling to model multiple non-overlapping regions of the background image scene is that it provides an accurate background representation as compared to background modeling using pixel-wise scalar value. Another advantage of the method for the present invention is that a less computational cost is used as compared to background modeling using pixel-wise statistical or kernel density. Furthermore, the method for the present invention has higher sensitive foreground detection as compared to privacy mask concept (masking out dynamic region from being modeled.
