Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Image improvement and restoration methods allow image quality improvement. Image restoration needs some information on the image or on the degradation whereas image improvement doesn’t need it. In this paper we talk about image improvement methods because sometimes it is an important stage before image restoration. Benin National Television Archieve Image has been taking as example. Different image improvement methods based on image histogram modification as: dynamique expansion, histogram adjustment, histogram specification etc, have been applied to the same televisual archive image for its quality characteristics improvement. In the work image noise didn’t have been taked in consideration. Programmation on Matlab has been used specifically the image processing toolbox. Whith the different methods applied only histogram adjustment and histogram specification gave the best results. Histogram adjustment conserve the image characteristics but doesn’t improve its visual aspects whereas histogram specification does it. In the conclusion; histogram as the first image analysis tool has been studied. Different histogram modification methods were applied. If they globally improve le visual aspect of image, they also allow access to image noises for a best processing
Security system is implemented to conceal sensitive text-information on personal computer (PC). It offers using normal multimedia image-based steganography to substitute the pixel least significant bits with text to be hidden. The paper includes various testing setups for possible increment in the ambiguity and capacity within steganography adopting choices of 1, 2, 3 and 4 least significant bits stego-systems. The design novelty is based on offering full security data for the user for selecting suitable cover-image from the PC in terms of the security priority. This method permits the PC user to examine multi-bits steganography on various pictures for concealing similar sensitive texts. Then, it becomes possible for the user to prefer one image for using as cover image in terms of his/her choice understanding the desired capacity and security importance. The study proofs the information dependence and its security property by testing 24 fixed sizes PC pictures indicating remarkable outcomes
