摘要
红外成像技术得了广泛的应用,为了获得高质量的红外图像,首先对红外图像进行去噪处理,抑制噪声的干扰,提高图像的对比度;然后对红外图像进行同态滤波增强处理,改善图像的视觉效果,使得边缘信息更加清晰,最后提取红外图像特征,并应用静脉图像等红外图像识别中。结果表明,红外图像质量得到了明显的改善,获得更加理想的特征,从而有利于提高静脉图像等的识别正确率,拒识率低,验证了本文方法的有效性。
Application of infrared imaging technology is widely, in order to obtain high quality of infrared image, the infrared image is denoised to suppress noise interference to improve the image contrast, and secondly the infrared image is homomorphic Filtering to improve the visual effect of the image and edge information is more clearly, finally, the features of infrared image are abstract to applicant the vein image identification. The results show that the infrared image quality was improved obviously, get more ideal features to improve the recognition rate of vein image, and verify the validity of the proposed method.
