PhD Research Title: Extracting Foreground in Video Sequence
Foreground detection is an important step in various video content analysis systems such as object tracking, recognition and counting. Due to the limitations of each algorithm based on its merits and demerits, so far, there is no consensus on the most effective method due to varying nature of videos. Accuracy and timely computational processing are the two main constraints. Whilst other methods only detect the approximate motion part(s) of object(s) in a video, our proposed approach detect the motion part(s) and associated object(s) to get the whole subject. The proposed technique uses a set of morphological operators to separate foreground and background. The proposed algorithm is an extension of my previous works [1]. A complex video sequence was tested to detect comprehensive foreground regions of moving object(s).
- Motion detection
- Noise removal
- Extraction of whole contour of foreground object
- Evaluation of our proposed approach with other state of the art techniques based on performance measures
For motion detection we use blockbased motion estimation technique. Due to no perfect motion estimation algorithm we have to use certain procedures to remove miscalculated areas of motion. Once we achieve those positions of the object where motion exists our next target is to extract the whole foreground object contour.
Correctness is an important step in evaluating the proposed algorithm. We are using 11 different performance measures [fig.3].
