Preprocessing is a significant operation in image analysis using CAD system and is a personal preference of a researches or software developer. The process to be implemented and the hierarchy of execution are determined by the programmer. Main objective of preprocessing is to remove unwanted artifacts and to increase the quality of MR image to be analyzed. Low quality images and unwanted regions provide unwanted information during noise analysis. For the effective execution of segmentation algorithms, the images must be preprocessed efficiently. In this paper proposed two analysis such as colorless model and color model. The color model provide the better result.

Improved linear iterative clustering and improved color based histogram equalization.
