iv Acknowledgements I am most indebted to my wife, Nathalie, who was on my side throughout this entire adventure. She has been extremely supportive and has accepted a great deal of hardship and sacrifices to give me the necessary time to complete this project. This is her accomplishment as well! At Caltech, my foremost thanks go to my advisor, Pietro(More)
Detecting humans in images is a useful application of computer vision. Loose and textured clothing, occlusion and scene clutter make it a difficult problem because bottom-up segmentation and grouping do not always work. We address the problem of detecting humans from their motion pattern in monocular image sequences; extraneous motions and occlusion may be(More)
We propose an EM approach combined with the modified separation matrix scheme to perform 30 motion segmentation of the image sequence which contains multiple moving objects. We observe that, given the detected features and their 2D optical flow, in most cases the objects or their flow are separated very well from each other in space. The separation matrix(More)
We address two issues in this report. One is the real time implementation of feature tracking and motion estimation. As a fundamental problem in vision eld, feature tracking needs to be implemented in real time so that researchers can do further analysis on motion such as building real time visual navigation system etc.. Our implementation of the algorithm(More)
Vision is a primary sense that allows human beings to interact with their environment and motion is one of the most important cues that vision can explore and utilize. In this thesis, we present computational approaches to the problems of inferring three-dimensional motion information and perceiving two-dimensional human motions from a sequence of images(More)
With the background of practical automatic control project of stage mechanical equipment in Qujing, Yunnan, P.R.China, high levels configuration software of Schneider Electric named Monitor Pro7 is introduced to accomplish the task of monitoring and controlling on site. Related structure diagram of the control system is shown and the function of Monitor(More)
This paper mainly presents an infrared sensor based bearing-only tracking approach based on bionics with single station system. First, an infrared sensor array based on insect's compound eye principle is designed. Then, an adaptive platform scanning mode is given. This mode based on gaze extends the range of space searching. Moreover, a registration(More)
