The two main factors that determine the quality of images from scaling algorithms are shape preservation and topology preservation. Most of the existing scaling algorithms focus on shape preservation and some pay attention to topology preservation. In this paper we propose a shrinking algorithm for binary images to preserve topology. The proposed algorithm shrinks the image by a factor of powers of...
This paper investigates a new interpolation technique based on content adaptive interpolation with fuzzy reasoning. The proposed technique reduces image artifacts in regions where moving object cannot be well traced by motion estimation. Our proposed method consists of two parts: content classification and fuzzy weight assignment process. The spatial deinterlacing methods have been studied excessively...
In this paper we present a robust pedestrian detection algorithm in low resolution on-board monocular camera image sequences of cluttered scenes. At first a motion based object detection algorithm is developed to detect foreground objects by analyzing horizontal motion vector. A cascade structure of rejection type classifier is utilized for our pedestrian detection system. Initial stage of cascade,...
New hierarchical method for detecting and classifying shot boundaries in video sequences using information theoretic classification (ITC) rule is proposed. ITC relies on likelihood of class label transmission of a data point to data points in its vicinity. ITC focuses on maximizing the global transmission of true class labels and classifying the frames into two classes of cuts and non-cuts. Applying...
