In recent years, communication in wireless is well improved technology for moving the data like text, image, video, and audio. But WN (wireless network), overload a important issues of packet loss traffic, high excellence video bandwidth limit are network surplus thread. To defeat these issues, Shih-Chia Huang Bo-Hao suggested PCA-related RBF method object identification (motion detection). This first changes bit rate as per level bandwidth. If more, then would be if minimum more. Also this...

Abstract Image segmentation is a critical process in computer vision. It involves dividing visible input into segments to simplify image analysis. Segments represent objects or parts of and comprise sets super-pixels. sorts pixels larger components, eliminating the need believe individual as units observation. Brain tumour crucial task medical segmentation. Early diagnosis brain tumours plays role improving treatment possibilities increases survival rate patients. Manual for cancer...

Shadows are formed when light from the source is obstructed by an object. hide information of underlying objects which will lead to wrong interpretations during image processing. Hence shadow detection has become a vital pre-processing step in digital processing as most images acquired contaminated with shadows. The shadows found more urban where surface elevation changes dramatically thus increasing complexity scenes. In this paper we discuss various techniques that have been used for both...
