The invention relates to a method for processing an image displayed by a display device comprising at least one light source and one light valve. It comprises the following steps: applying a compression factor C to the grey levels of the image video signal that are higher than a threshold ...
Image processing apparatus for correcting captured image An image processing apparatus selects a correction method of a defective pixel in accordance with the type of the defective pixel. The image processing apparatus includes an imaging device consisting of a plurality of pixels, a storage d... ...
A problem in digital image processing employing a tone reproduction function that maximizes the quality of the processed image is to automatically determine the overall contrast of the processed image. In an improved method for determining the contrast of the processed image, the contrast is automatica...
假设X表示我们的输入图像,其亮度l的变化范围是lmin到lmax,那么这个算法一共分为5步来执行: 二、原始版本算法步骤: 假设X表示我们的输入图像,其亮度l的变化范围l_{min}和l_{max},那么这个算法一共分为5步来执行: 2.1、Image Statistics Computation 图像X(i,j),亮度灰阶I的动态范围是l_{min}和l_{max},...
(CDR).Pixel value distributions were measured for various tissue thicknesses of a dental quality assurance jaw phantom and the average pixel values and SNR calculated.Equalization resulted in enhanced image contrast of underexposed images by effecting pixel value adjustment with little change in SNR. ...
(FIR) filters. Compact support helps improve the computational complexity of the transform. Symmetry property of the filtercoefficientsis desirable since it results in linear phase transfer function. In image processing, the linear phase filters produce fewer visual artifacts [37–39]. The proposed ...
