Looks like your segmentation is not so good, or it's only partially finished. But you only attached the segmented image, not the original one. It looks like a frame from a video. In that case you can find the background frame fairly easily, then subtract it from your actual frame with imabsdiff. If you know there are only a certain number of people in the frame or if you want to throw out blobs smaller than a certain size you can use bwareafilt.

There is also a foreground detector in the Computer Vision Toolbox, as well as grabcut, lazysnapping, and activecontour in the Image Processing Toolbox. Try them.

Thank you sir, I already can remove the bacground using imabsdiff. and then i filter the image using medfilt2 and then remove object that smaller than 300 using bwareopen.
