Description: 本文将小波图像分解和信息熵特征提取相结合,提出一种新的掌纹特征提取算法。该算法首先对掌纹灰度图像进行二维小波分解,再利用多分辨信息熵分别计算不同尺度下的能谱熵作为特征向量,从而实现掌纹特征提取。该算法不但避免了图像增强和纹理细化等预处理过程,而且运用多分辨信息熵的自适应计算方法来调节分解级数,使得到的特征向量长度远小于传统算法。-In this paper, wavelet image decomposition and information entropy feature extraction combined propose a new feature extraction algorithm. The algorithm first palmprint grayscale image two-dimensional wavelet decomposition, reuse multiresolution information entropy were calculated at different scales of the energy spectrum entropy as feature vectors, enabling feature extraction. The algorithm not only avoids the preprocessing such as image enhancement and texture refinement process, and the use of multi-resolution information entropy adaptive calculation method to regulate the decomposition level, so that the length of the feature vector obtained is far smaller than the conventional algorithm.

Description: In this paper, we describe an approach to the problem
of simultaneously enhancing image sequences and tracking the objects of interest represented by the latter. The enhancement part
of the algorithm is based on Bayesian wavelet denoising, which
has been chosen due to its exceptional ability to incorporate diversea prioriinformation into the process of image recovery Platform: |

Description: 这篇论文提出了一种较好的水下图像增强的方法。首先使用经过端到端训练的卷积神经网络去测量输入图片,同时以自适应双边滤波器对传输图片进行处理。接着提出一种基于白平衡的策略来消除图片的颜色偏差,用拉普拉斯金字塔融合获得无雾和色彩校正图像的融合结果。 最后,输出图像被转换为混合小波和方向滤波器组(HWD)域,用于去噪和边缘增强。 实验结果表明,该方法可以消除颜色失真,提高水下图像的清晰度。(This paper proposes a better underwater image enhancement method. Firstly, an end-to-end training convolutional neural network is used to measure the input image, and an adaptive bilateral filter is used to process the transmitted image. Then a strategy based on white balance is proposed to eliminate the color deviation of images. The fusion results of fog-free and color correction images are obtained by Laplacian pyramid fusion. Finally, the output image is converted into hybrid wavelet and directional filter bank (HWD) domain for denoising and edge enhancement. The experimental results show that the method can eliminate color distortion and improve the clarity of underwater images.) Platform: |
