With the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. Therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. Tracking people as they move through a camera network with non-overlapping field...

Image capture devices poor-quality images under low-light conditions, and the resulting have dark areas due to insufficient exposure. Traditional Multiple Exposure Fusion (MEF) methods fuse with different exposure levels from a global perspective, which often leads secondary in well-exposed of original image. At same time, image sequences are not sufficient, MEF method is limited by training da...

This paper describes a process for extracting hybrid color features for natural scene images. There are different approaches to color feature analysis are tested on the classification of image from Oliva, Antonio Torralba database. For this purpose three set of image categories are taken viz coast, river, and mountains. The first method employs multispectral approach, in which image features ar...

This paper proposes two new compressed-domain features for color image retrieval based on the YCbCr color space. They are named Multi-Stage Vector Quantization Index Histograms (MSVQIH) and Mean-Removed Vector Quantization Index Histograms (MRVQIH). For each color component, to obtain the MSVQIH features, we extract two MSVQ Index histograms from the two stage VQ index sequences respectively. S...

In this article, the color space influence on different methods of morphological hierarchical segmentation is studied. For this purpose, several experimental studies are carried out on hundred images of the ‘Berkeley Segmentation Dataset and Benchmark’’ (Berkeley). On one hand, four usual and representative color spaces (RGB, YCbCr, L*a*b*, IHSL) are considered. On the other hand, three differe...

This paper presents a novel color face recognition algorithm by means of fusing color and local information. The proposed algorithm fuses the multiple features derived from different color spaces. Multiorientation and multiscale information relating to the color face features are extracted by applying Steerable Pyramid Transform (SPT) to the local face regions. In this paper, the new three hybr...

A novel digital watermarking for ownership verification and image authentication applications using discrete wavelet transform (DWT) is proposed in this paper. Most previous proposed watermarking algorithms embed sequences of random numbers as watermarks. Here binary images are taken as watermark for embedding. In the proposed approach, the host image is converted into the YCbCr color space and...
