However, portrait complexion is sallow (not only white balance problem, but also color tendency and brightness), emerald green is yellow, red is saturated and loses level.Among them, portrait photography is particularly troubling. The concrete manifestation is,First, high-gloss area contrast is not high, the characters face the whole side

Itzik Ben-Gan Similarly, with histograms, you can analyze the sampling of performance counters (such as CPU utilization and memory) set on the server in the network. For example, assume that you record the CPU usage of a network server every five minutes, and the value measured on a certain day changes between 21% and 100%. You can generate a histogram with four levels-20 to 40, 40 to 60, 60 to 80, and 80 to 100-to obtain the number of samples of each

Given n non-negative integers representing the histogram ' s bar height where the width of each bar is 1, find the Area of largest rectangle in the histogram.Above is a histogram the where width of each bar is 1, given height = [2,1,5,6,2,3] .The largest rectangle is shown in the shaded area, and which has an area = 10 unit.For example,Given height = [2,1,5,6,2,3] ,Return 10 .Train of thought: This problem

resolution. Comparison of official MTF curves of Nikon 18-70 and Sigma 17-70HSM lenses 101 about MTF: I have never insisted that movie friends go to the "lens" MTF Curve, because it is easy to "get angry" and regard it as the "final test standard of the camera", ignoring the comprehensive evaluation of the camera.
