Hyperspectral unmixing (HSU) plays an important role in hyperspectral image (HSI) analysis. Recently, the HSU method based on sparse regression has drawn much attention. This paper presents a new weighted sparse regression problem for HSU and proposes two iterative reweighted algorithms for solving this problem, where the weights used for the next iteration are computed from the value of the current...
Recently most license plate extraction algorithms are proposed under some certain conditions. This paper proposes a license plate extraction method that can be self-adaptive to images with various sizes under different illumination conditions. First, a morphology based image preprocess is applied for background elimination. Then we get the level clipping by a self-adaptive binary thresholding the...
A new method which can enhance the contrast between a target and its background robust to noise is explored by using the a acute trous algorithm and modified seeded-region-growing algorithm. The target can be extracted ultimately with this method. This article also shows the precision and the effectiveness of the proposed method in extraction dot and spot target in a single frame by the experimental...
