摘　　要：针对手势灰度图像的纹理特征富含手势类别信息的特点,提出一种基于融合GLCM(灰度共生矩阵)和Gabor小波变换提取手势图像空、频域纹理特征的手势识别方法。构建手势灰度图像的多方向共生矩阵,并计算多方向共生矩阵的特征参数来提取手势纹理的GLCM特征;通过手势灰度图像的Gabor小波变换来提取手势纹理的Gabor特征;对所提取的两种特征进行归一化处理后串联构建手势纹理特征向量;使用基于稀疏自动编码器和softmax分类器的深度堆栈自编码网络对构建的手势纹理特征向量进行分类识别。实验表明:该方法具有较高的识别率和较好的鲁棒性,对15种手势的平均识别率达到97.4%,能够满足人机交互对手势识别的要求。For the characteristic that the texture feature of gray gesture image is rich in the information of gesture category,a gesture recognition method based on fusion of Gray-level Co-occurrence Matrix(GLCM) and Gabor wavelet transform was proposed to extract spatial and frequency domain texture features of gesture images. We,constructed multi-direction co-occurrence matrix of gesture gray image and calculated feature parameters of multi-direction co-occurrence matrix to extract GLCM features of gesture texture. The Gabor features of gesture texture was extracted by Gabor wavelet transform of gray gesture image. Then,the two extracted features were normalized to construct the feature vector of gesture texture in series. The deep stack encoder network based on sparse encoder and softmax classifier was used to classify and recognize feature vector of gesture texture. Experiments show that the proposed method has high recognition rate and good robustness,with the average recognition rate of 97.4% among fifteen gestures,which can meet the requirements of gesture recognition for human-computer interaction.
