Kurdthongmee, W. A real-time system is a computer system that monitors or controls an external environment. The system must meet various timing and other constraints that are imposed on it by the real-time behaviour of the external world. One of the differences between a real-time and a conventional software is that a real-time program must be both(More)
Parts of a self-organizing map (SOM)-based quantizer can be performed in parallel, i.e., distance calculation between an input pixel and a group of codewords or processing elements (PEs), and updating codewords. To search for the best matching unit (BMU) whose distance is the minimum, all distances are inevitably required to compare with each other. It is(More)
Many techniques have been proposed to quantize a digital colour image in order to reduce the representative number of colours to be suitable for presenting on different types of display screens. In addition, the techniques have been used to significantly reduce the amount of image data required to transfer over a communication network. Most of the published(More)
