摘要：The paper underneath deals with image processing of color images using DSP processor (Texas Instrument product, TMS3206713). The basic process involve is to take input, a color image which is to be enhanced in DSP board and output its enhanced form which can be displayed on VM3224K2 Daughter kit (LCD). VM3224Daughter Kit is embedded with DSK6713 Kit just to display the respective images. Enhancement of color images can be carried out either in spatial domain or frequency domain. Enhancing color images in frequency domain is advantageous because individual color/frequency components can be modulated as per the requirement. Color images are analyzed into its constituent intensity and color components. Suitable scaling factor are employed for different components so that over all image is enhanced. Color images mostly uses JPEG compression format for saving bandwidth and memory space which uses popular discrete cosine transform (DCT). Hence it becomes necessary to investigate and propose new enhancement technique for the color image enhancement in compressed domain. In order to observe the colorfulness of the image, colorfulness metrics is adopted after enhancing the color image in compressed domain. The enhancement technique & proposed algorithm were well implemented practically on our hardware (TMS6713 kit). Implementation of algorithm& all computation of the paper is carried out in C-programming language
