Abstract(in English) | When pattern recognition is achieved by conventional techniques, processing time becomes long and it is difficult to design an LSI. In the present research, the associative memory architecture for finding the most similar data among previously stored reference data is investigated for an application involving recognition and learning. We achieve high speed, low power consumption and a small area for the recognition function by using a mixed digital-analog fully parallel associative memory. For implementing the learning function of new reference data, we propose an associative memory based learning algorithm which imitates the concept of human's short/long-term memory. We apply the proposed learning algorithm to codebook-based image compression for evaluation and analysis of its efficiency. The created codebook with the proposed learning algorithm is evaluated for capturing the learning effect quantitatively with the Peak Signal Noise Ratio (PSNR). PSNR is an index of the image quality, and it can analyze the learning parameter dependence. In addition, we apply Huffman Coding to the codebook-based image compression, and verify that the compression ratio is improved from 12.8 to 14.1. |
