Abstract: Image Processing (IP) is a method to perform some operations in the image for enhancing the clarity or extract the beneficial data from the image. Several methods are already available to enhance the quality of an image. Data transmission of an image is difficult when the size of the image becomes large. So, image compression is introduced the 3 Dimensional Discrete Wavelet Transform (3D DWT). The 3D DWT based image compression is used because of its higher coding efficiency and also better recovery of image. Image compression is used to compress the image size using either lossless or lossy image compression based methods. There are various compression methods available for reducing the image size. This study presented a survey of various methods which exist in the field of IP over FPGA and issues associated with individual methods.
