Due to the increasing requirements for transmission of images in computer, mobile environments, the research in the field of image compression has increased significantly. Image compression plays a crucial role in digital image processing, it is also very important for efficient transmission and storage of images. When we compute the number of bits per(More)
Compressing an image is significantly different than compressing raw binary data. compressing images is used by this different compression algorithm. Wavelet transforms used in Image compression methods to provide high compression rates while maintaining good image quality. Discrete Wavelet Transform (DWT) is one of the most common methods used in signal(More)
We cannot operate the whole image directly in some applications like image recognition or image compression because it is inefficient method. Therefore, before recognition or compression, many image segmentation algorithms were suggested to segment an image. Image segmentation operation is to rate or cluster an image into many regions depending on the(More)
In This paper we propose an improved E-Learning Social Network Exploiting Approach based on clustering algorithm and graph model, which can automatically group distributed e-learners with similar interests and make proper recommendations, which can finally enhance the collaborative learning among similar e-learners. Through similarity discovery, trust(More)
Many improvements on image enhancemen have been achieved by The Non-negativity And Support constraints Recursive Inverse Filtering (NAS-RIF) algorithm. The Deterministic constraints such as non negativity, known finite support, and existence of blur invariant edges are given for the true image. NAS-RIF algorithms iterative and simultaneously estimate the(More)

Personal identification process is a very important process that resides a large portion of daily usages. Identification process is applicable in work place, private zones, banks …etc. Human is a rich subject having many features that can be used for identification purpose such as finger vein, iris, face …etc. In this paper, a personal identification system(More)
