A Novel Color Image Compression Method Using Eigenimages
Since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–D realization. Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. In this paper, first a method is prop...
متن کاملMEDICAL IMAGE COMPRESSION: A REVIEW
Within recent years the use of medical images for diagnosis purposes has become necessity. The limitation in transmission and storage space also growing size of medical images has necessitated the need for efficient method, then image Compression is required as an efficient way to reduces irrelevant and redundancy of the image data in order to be able to store or transmits data. It also reduces...

متن کاملImage Compression Using Dwt
In the image processing image compression is very important. Because of image compression image quality may effect and CR may vary. Here DWT is used for compress the image i.e. used "haar wavelet” with decomposes level 2 which makes it more compressible. Huffman encoding is used to decrease length of data and also changed threshold values and set it to 10.This is the only approach proposed for ...
متن کاملImage Compression Using Wavelets
Image compression is a fast paced and dynamically changing field with many different varieties of compression methods available. Wavelet transform techniques currently provide a promising approach to image compression and concentrate on achieving higher compression ratio without sacrificing the quality of the image. In image compression, the choice of wavelet depends on the image content. The q...
