Image Compression based on SVD and MPQ-BTC

In this paper we will provide a new way of images compression based on two mathematic concepts, these two concepts are Singular Value Decomposition (SVD), and Block Truncation Coding. The input image either is in JPEG format or in BMP format, and the current way suitable for both color and gray scale images. The input image will be compressed first by reducing the image matrix rank, which achie...

Rgb & Gray Scale Component on Mpq-btc in Image Compression

Block Truncation Coding (BTC) is novel digital technique in image processing using which images can be coded efficiently. BTC has played an important role in the sense that many coding techniques have been developed based on it. Its main attraction being its simple underlying concepts and ease of implementation. We perform compression using two level quantizer and proving minimum Peak Signal No...

A variation on SVD based image compression

We present a variation to the well studied SVD based image compression technique. Our variation can be viewed as a preprocessing step in which the input image is permuted as per a fixed, data independent permutation, after which it is fed to the standard SVD algorithm. Likewise, our decompression algorithm can be viewed as the standard SVD algorithm followed by a postprocessing step which appli...

Hybrid KLT-SVD image compression

This paper investigates a transform adaptation technique, applied to transform coding of images, as a way of exploiting the variation in local statistics within an image. The method makes use of the relationship between KLT and SVD, and their energy compaction properties. We compare this approach to a standard KLT coding system. Motivated by increased coding e ciency an analysis-by-synthesis ap...

Normal map compression based on BTC and wavelet coding

Normal mapping is a powerful technique for simulation of surface roughness by means of normal maps. The high polygon count model is represented by coarse polygon mesh with fine details stored in the normal map. Thus, the technique greatly reduces geometric complexity of models and shifts the demands on effective normal map compression algorithms. In this paper we present normal compression algo...
