说明：  时间排序 (Time to sort)

用汉明窗作的语音去噪低通滤波器，matlab程序（自己做的，复制到.m文件，完全可运行）(Hamming window used for speech denoising low-pass filter, matlab program (their own, and copied to. M documents, completely run))

结合PCA的尺度不变特征变换(SIFT)算法源代码，可用于图像目标检测和识别。(combine PCA scale-invariant feature transformation (metabolism) algorithm source code, images can be used to target detection and identification.)

说明：  引入具有平移不变性和良好的方向分析能力的双树复小波变换对源图像进行多尺度分解;然后对分解得到的各尺度的高频子带采用基于跨尺度的邻域空间频率的融合策略,最高层的低频子带采用基于改进的邻域熵的融合策略进行融合处理;最后对融合后的各个频带进行双树复小波逆变换,重构出融合图像(The dual tree complex wavelet transform with translation invariance and good direction analysis ability is introduced to decompose the source image in multi-scale; then the fusion strategy based on the cross-scale neighborhood space frequency is adopted for the high-frequency subband of each scale obtained by decomposition, and the fusion strategy based on the improved neighborhood entropy is adopted for the low-frequency subband of the highest level; finally, each frequency band after fusion is carried out Double tree complex wavelet inverse transform to reconstruct fusion image)
