| 摘 要： | EHMM人眼状态识别算法具有较高的识别率但算法复杂,因此利用SOPC开发平台设计了一种基于行列变换快速算法的2D-DCT IP核以提高处理速度;根据眼状态识别只需取2D-DCT后左上角部分子矩阵数据的特点,对其计算过程进一步优化;并引入了转置存储技术,浮点数乘法通过移位后转化为定点乘法器实现,优化了硬件资源,提高了处理速度;实验结果表明该IP核很好地实现了人眼图像灰度值的DCT变换。

| Abstract: | Eyes' status identification algorithm based on EHMM(Embedded Hidden Markov Model) has high recognition rate but very complex,therefore,to enhance processing speed a 2D-DCT IP core with fast transform algorithm is implemented on SOPC platform.Since the eyes' status recognition only need the to Pleft corner partial matrix of DCT transformation,the computational process is further optimized.By the using of transposition storage technology and using the fixed-point multiplier instead of the floating number mult... |
