This paper introduces a combination of two new scrambling techniques to produce both obscured and incomprehensible scrambled JPEG image. The techniques are called Combined-Reverse-and-Normal- Direction (CRND) Zigzag and Quantized Blocks Permutation (QBP) scrambling. The scrambling techniques are easy to be implemented and by combining both techniques, the(More)
Conventional surveillance system requires human power to monitor and thus not applicable for a long hour monitoring. An automated method is proposed here, an integration of a moving object detection and recognition. First, the moving object is detected and segmented by using selectiveness adaptive background subtraction technique followed by noise and(More)
