105; the filter resamples a first image data signal 110, by a resampling factor, and outputs an image data signal 120 with a sample rate different to the first signal; the filter also applies a phase alteration to the first image data signal, to compensate a group delay in the signal. ...
Source objects upload still image frames to OpenGL ES as textures, then hand those textures off to the next objects in the processing chain.*/ 类中工具函数runSynchronouslyOnContextQueue等,通过dispatch_get_specific防止死锁,注意不要用dispatch_get_current_queue; 通过对三个典型类的作用解读,分别为(GPU...
Drag over the area you want to reconstruct. Pixels move more quickly at the brush center. Shift-click to reconstruct in a straight line between the current point and the previously clicked point. More like this Blend and fade filter effects ...

ND filters can help you create dramatic images when used well. If you find the correct exposure in-camera with an ND filter, you’ll get a higher image quality than you would if you adjusted your light settings in post-processing software. ...

#5237 implements a Gabor filter for image processing. From the comments and through my own use, the implementation seems to have limited freedom, and also the variances are defined in the original x,y instead of the rotated x', y' directions. The code is a modified version based on ...

A median filter is a type of order-statistic filter used in image processing to replace the center pixel of a neighborhood with the median value of the window, effectively removing specific types of noise like Gaussian, random, and salt and pepper noises from images. ...
