چکیده

With the advent of complex medical imaging and high speed video teleconferencing, there is an emerging need for fast colour image compression algorithms. This paper employs a self-organising neural network to achieve colour image segmentation and image data compression, with an adaptive codebook for faster training. Neural network architectures are well suited to high speed processing because they are massively parallel.

Kohonen Neural Networks for Optimal Colour Quantization

We present a Self-Organizing Kohonen Neural Network for quantizing colour graphics images. The network is compared with existing algorithmic methods for colour quantization. It is shown experimentally that, by adjusting a quality factor, the network can produce images of much greater quality with longer running times, or slightly better quality with shorter running times than the existing metho...

Adaptive Image Compression Using Neural Networks

In this article applying neural networks in order to compress images adaptively based on their entropies has been studied. A three-layer perceptron network is used basically, to compress the blocks of Images. In order to improve such a network, we have used various networks with different compression ratios, for the image with different complexities and details. In order to measure the complexi...
