Image Compression And Signal Classification By Neural Networks And Projection Pursuits, M. Fardanesh, O. K. Ersoy
Image Compression And Signal Classification By Neural Networks And Projection Pursuits, M. Fardanesh, O. K. Ersoy
Department of Electrical and Computer Engineering Technical Reports
In this report, two applications of neural networks are investigated. The first one is low bit rate image compression by using neural networks and projection pursuit. The second one is improving the classification accuracy of neural network classifiers by using unlabeled data. In the first part, a novel approach for low bit rate image coding is presented. The image is compressed by first quadtree segmenting the image into blocks of different sizes based on two activity measures , and then constructing a distinct code for each block by invokin~gth e theory of projection pursuit. The two activity measures used in …

Vlsi Implementation Of Discrete Cosine Transform Based On The Shared-Multiplier Algorithm, Sze-Po Hung, Wen-Zen Shen, O. K. Ersoy
Vlsi Implementation Of Discrete Cosine Transform Based On The Shared-Multiplier Algorithm, Sze-Po Hung, Wen-Zen Shen, O. K. Ersoy
Department of Electrical and Computer Engineering Technical Reports
In this paper a new algorithm for discrete cosine transform (DCT) is proposed. This algorithm is especially efficient for VLSI implementation because each multiplier in @e 1-D DCT is shared by two constants rather than one. This greatly reduces the chip area, and the high speed characteristics are still retained. Based on this algorithm, we have developed the corresponding bit-parallel, fully-pipelined architecture for the size-8 DCT. The core area of the chip is only 8.6mm x 8.5mm, using 1.2um double-metal single-poly CMOS technology. This chip is simulated for operation at the maximum speed of 100 MHz which far exceeds the …
