In order to further improve the recognition rate and computing efficiency of modular 2DPCA in face recognition, an improved modular 2DPCA method based on image segmentation is proposed. Firstly, segmentation of threshold value optimization is utilized to segment face image of training samples into several non-overlapping sub-image spaces so that the pixel number has uniform distribution in each sub-image...
Using the computer graphic processing technology, the detection of river sand content is proved. After using the submarine photograph method ingestion overflow cross section video information source material, carries on processing and the analysis using the wavelet denoising algorithm to the image, it can measure the number of particles of sediment, sediment particle shape and size of each. Then it...
In this paper, we propose a novel palmprint verification scheme named as Orthogonal Code based on multiple 2D Orthogonal Gabor Phase feature. A palmprint image contains various features with multiple orientations, so only a single orientation in the palmprint can not distinguish a subject well. The 2D Orthogonal Gabor filters with different orientations are employed to extract texture information...
