Finger-vein biometric identification using convolutional neural network
TL;DR: In this article, a CNN with fused convolutional sub-sampling architecture was proposed for finger-vein recognition, which achieved an accuracy of 99.38% with an error ratio of 80/20 percent for separation of training and test samples.

Color image histogram equalization by absolute discounting back-off
TL;DR: A novel color image histogram equalization approach is proposed that exploits the correlation between color components and it is enhanced by a multi-level smoothing technique borrowed from statistical language engineering in order to eliminate the gamut problem.

Contrast adaptive binarization of low quality document images
Mengling Feng,Yap-Peng Tan +1 more
TL;DR: An improved method for binarizing document images by adaptively exploiting the local image contrast is proposed, which aims to overcome the common problems encountered in low quality images, such as uneven illumination, low contrast, and random noise.
