Application For Image Compression Based On Wavelet Yransform

The image as delivering medium and means of information are very important .But the data quantity of the numerical image is very big, needing a lot of ratios to especially count, as a result need to carry on the compression to the image. So-called image compression is at guarantee the certain image quantity and satisfy the premise of certain request under, a process of reducing the quantity of original data of image .Aiming at the existent and related redundancy information in the image s, adopting a certain method to do away with the surplus composition, can carry out the compression of the image. Though the saving technique of data develops continuously, the letter way delivers the bandwidth to widen continuously, people for the compression image data with economical data saving the space and exaltations believe the need of an utilization to increase still.Image compression is one of the key techniques in today's digital image-processing field, which has been applied widely. The research over last two decades has proved great significance of this technique. Image compression included loss compression and lossless compression .The traditional image compresses of adopting the DCT transformation to code would appear "a block effect", the efficiency compress at the same time is also not high, a wavelet image coding is in recent years along with a development and analyzes of the wavelet...
