Biography

I am a first-year PhD student in Computer Science at University of Illinois Chicago. Currently, I am also working as a Teaching Assistant in Computer Science Department at the University of Illinois Chicago. I have completed my B.Sc. in Computer Science and Engineering from Bangladesh University of Engineering and Technology(BUET).

My research interests lie in the intersection of causal inference, data science, and machine learning. In particular, I am interested in causal reasoning with data that can answer questions and/or solve problems in e-commerce, social media, social science, and healthcare domains. I am fascinated in applying econometrics methods for answering causal questions with data that can reason the past, and also provide insights for the future. I am also interested in protecting user data privacy in software applications.

Scene Reconstruction From Multiple Static CCTV Cameras

Supervisor : Dr. Md. Monirul Islam

Collaborator : Anwar Hossain

Keywords : Scene Reconstruction, Missing Scene Construction, Video Processing, Object Monitoring, Object Tracking, Surveillance System, Polyfit

Flowchart of the System

We have introduced and developed a system that can present information of a human or an object to a user or visual inspector by analyzing videos taken from multiple sequential or partially overlapping static CCTV data from area of interests. It can reduce manual effort of visual inspector on visual surveillance system. For implementing the system, we need to recognize the input object in different video files taken from CCTV cameras. For recognizing the input object from frame to frame in video files, we have used Speeded Up Robust Features(SURF). The recognized object in a frame has been used as a new input for recognizing the input object in next video frame so that the input object can be detected more accurately using SURF as object shape or orientation can be changed over time. If there is a place in the area of interests where camera is defective or unavailable, we have developed a movement prediction algorithm for predicting the movement of the input object in that specific place using the objects previous or next velocities in different cameras. For determining the average velocity of the input object in a camera, we have considered the total changes of pixels over time and then converted the pixel distance to actual meter distance. As meter distance between two pixels is not constant in relative to the center of the camera, we have built a four degree polynomial approximation to determine meter distance from pixel distance. We have used these average velocities of the input object from different cameras to predict the movement of the object in the place of missing or defective camera on given the background information of that place.
