Whiteboard Disclosure using Background Subtraction and Object Tracking
نویسندگان
چکیده
Online video lectures are becoming commonplace in higher education. One problem is that the instructor might block what he has written on the board. In our project, we reconstruct the online lecture video so that the information on the whiteboard is always available to the viewers. The background subtraction, object tracking, and object replacement technique have been used to reconstruct the movie. The algorithm is successfully implemented for different board conditions and video resolutions. Our implementation provides a useful feature to students who take online courses.

Moving Objects Tracking Using Statistical Models
Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...

متن کاملA Novel Method for Tracking Moving Objects using Block-Based Similarity
Extracting and tracking active objects are two major issues in surveillance and monitoring applications such as nuclear reactors, mine security, and traffic controllers. In this paper, a block-based similarity algorithm is proposed in order to detect and track objects in the successive frames. We define similarity and cost functions based on the features of the blocks, leading to less computati...
متن کاملUsing a Novel Concept of Potential Pixel Energy for Object Tracking
Abstract In this paper, we propose a new method for kernel based object tracking which tracks the complete non rigid object. Definition the union image blob and mapping it to a new representation which we named as potential pixels matrix are the main part of tracking algorithm. The union image blob is constructed by expanding the previous object region based on the histogram feature. The pote...
متن کاملDetection and Tracking of Moving Object Based on Background Subtracion
The proposed work presents a survey on moving object detection and tracking methods. It is classified into different categories and new trends identify. This work shows moving object detection and tracking using different and efficient methodologies. Object detection and object tracking is used to track the object type(such as human, vehicles) and detect the movement of the object(such as movin...
