Abstract:


This paper presents a robust and optimized data compression and suppression based on DCT and Image overlapping methods to transfer panorama images through the Wireless Sensor Networks (WSN). First, we will receive the input images in a fixed interval of times and then we apply two compression algorithms to achieve a compressed and transferable panorama images taken from eight different directions. Our Proposed Algorithm can compress the size of original panorama images up to thirty percent while the vital color information as well as the quality of the original images can be preserved .The panorama image quality and the size of compressed image are two main issues that need to be considered during the process of the panorama image compression. Our DCT-Overlapped Panorama Image compressing Algorithm consists of two major compressing levels of image compression and Overlapping using DCT and our new Overlapping techniques.
