Development of IC Chip with human visual function for High-speed fish Recognition

构建了一种新的具有人类视觉功能的彩色图像处理系统，并将其应用于形状相似但颜色和/或图案不同的鱼类的模式识别。该系统具有图像可变分割的功能。因此，加工区域的大小、位置、数量和控制策略(如SIMD、MIMD等)可以针对每个加工任务灵活动态地改变。在该应用中，首先提取鱼的形状特征，然后从鱼的几个小区域中提取颜色特征。结果表明，所提出的算法和彩色图像处理系统具有较好的实用性，可用于鱼类的分类，每条鱼的识别时间小于70ms。

A new color image processing system with human visual function is constructed and applied to the pattern recognition of fish species, the shapes of which are very similar but the colors and/or patterns of which are different. This system has a function of variable partition of a picture. Therefore, the size, position, number of processing regions and control strategy such as SIMD, MIMD, etc. can be varied flexibly and dynamically for each processing task.The high-speed feature extraction of fish is examined as an example of the application of the proposed system. In this application, the shape features of fish are extracted at first., and then the color features are extracted from several small regions of fish. As a result, it is clarified that the proposed system can be used in practice in order to classify fish species at a high speed.As a result, it is clarified that the proposed algorithm and color image processing system are satisfactorily useful can be used in practice in order to classify fish species and that the recognition time less than 70ms per a fish is achieved.
