CIFilter with UISlider

由 若如初见. 提交于 2020-01-03 10:17:09
问题 So I have a UISlider that is changing a HUE using CIFilter. Its insanely slow because I'm affecting the base image while the uislider is in use. Any one have suggestions on how to do this more efficiently? // UI SLIDER -(IBAction)changeSlider:(id)sender { [self doHueAdjustFilterWithBaseImage:currentSticker.image hueAdjust:[(UISlider *)sender value]]; } //Change HUE -(void)doHueAdjustFilterWithBaseImage:(UIImage*)baseImage hueAdjust:(CGFloat)hueAdjust { CIImage *inputImage = [[CIImage alloc]

What is the best way to change the color/hue of an image on canvas?

由 吃可爱长大的小学妹 提交于 2020-01-03 04:46:28
问题 I tried googling for an answer, but I never was able to find a plain answer, or why the answer works. So I would like to know, what is the code that one would use to change the color of an image on canvas? For example, lets say I want to change things to #ff0000 . If a pixel is #000000 , it should stay that way. If a pixel us #ffffff , it should become #ff0000 . Here is my text object constructor: Text = function(x, y, str, s, c){ var img = new Image(); img.src = "font.png"; var alphabet = [

How to calculate mean and standard deviation for hue values from 0 to 360?

由 吃可爱长大的小学妹 提交于 2020-01-01 05:23:07
问题 Suppose 5 samples of hue are taken using a simple HSV model for color, having values 355, 5, 5, 5, 5, all a hue of red and "next" to each other as far as perception is concerned. But the simple average is 75 which is far away from 0 or 360, close to a yellow-green. What is a better way to calculate this mean and associated std? 回答1: The simple solution is to convert those angles to a set of vectors, from polar coordinates into cartesian coordinates. Since you are working with colors, think of
