Abstract

The paper addresses the area of image compression and decompression using hybrid algorithm as it is pertinent to different grounds of image processing. On the basis of evaluating and analyzing different image compression techniques this paper presents the hybrid technique applied to different sets of images for compression and decompression. It also includes various benefits such as minimizing the size in bytes of a graphics file without degrading the quality of the image to an undesirable level. This devaluation allows more images to be stored in a given amount of memory space. Image compression involves the identification and removal of redundant and unnecessary elements of source image. A software algorithm has been refined and implemented to compress and decompress the given image using hybrid techniques in MATLAB software.

Abstract

An attempt has been made to present a case study for enhancing quality of teaching-learning process, where a structured approach has been adopted, putting emphasis on the factors 'knowledge', 'research' and 'experience' for teaching the subject 'Embedded Real time operating systems' to PG (Post graduate) students. Our aim is not only to enhance quality of teaching-learning, but also to strengthen the knowledge domain of the students, augment their research quality and skillsets through experiences in diversified ways. It has been proved that our structured approach not only addresses maximum program outcomes (those were, otherwise, not mapped through course outcomes), but also has motivated our students to acquire many skills required for their employability and enhance their global mobility.
