Investigations have shown that the back-scattering noise is sensitive to high-pass filter. In this paper, we proposed a new approach for underwater image denoising by combining wavelet decomposition with high-pass filter. Thereby both the low-frequency components of the back-scattering noise and ...
Filter: mainly for image processing Simple: similar toFilter, but focus on the overall characteristics of the image, such as the operation of the ROI, the operation of the false color, the area measurement, or the three-dimensional analysis of the entire image stack, visualization, and so on...
[Image-enhancement] Underwater image enhancement with global--local networks and compressed-histogram equalization, Signal Processing: Image Communication 2020. 1.3.2 Statistical Gradient Feature Statistical features of high-quality image intensity have strong sparsity, which means the feature map or statist...
(Middle) The refractive power of the eye varies with wavelength of light, essentially as if the eye were composed of water. Average axial chromatic aberration of 12 eyes. Data fromBedford and Wyszecki (1957). (Bottom) Chromostereopsis. A target P, not on the optic axis of either eye, em...
The pollution process and mechanism of underwater images is very complex.The noise under different underwater environment is not the same.The wavelet threshold de-noising method is used to denoise from underwater images and to improve the image quality.The wavelet threshold de-noising is an import...

FIGURE 6-32.The REDUCE and EXPAND procedures as defined inBurt and Adelson (1983). Any spatial filter can be used, but these examples use the Gaussian window ofEq. (6-39). The process used to create and reconstruct one level of the Gaussian pyramid from another level is shown inFig. ...
In this section, we first briefly review the guided image filtering algorithm; then, we analyze the properties of the guided image filtering with different parameter settings. 2.1. Guided Image Filtering The guided image filter [23] assumes that the filtering output follows a local linear model ...
In the field of microscopy images protection, Pizzolante et al. [12] introduced a novel watermarking scheme to embed the watermark information into the confocal microscopy image. Traditional watermarking algorithms have robustness to the common attacks, such as noise addition, filter operation, cropping...
