How to blur UIImage excluding specific point.

In GPUImageGaussianSelectiveBlurFilter how to set the point of non image blur ? i tried setting the point excludeCirclePoint but everything gets blur. I want to implement touches gesture and the touched point remains good while the other image gets blur.

You have to assign CGPoint to filter's excludeCirclePoint property where CGPointMake(0, 0) is the top-left corner of the image and CGPointMake(1, 1) is the bottom-right corner.

Something like:

GPUImageGaussianSelectiveBlurFilter *filter = [[GPUImageGaussianSelectiveBlurFilter alloc] init];
filter.excludeCirclePoint = CGPointMake(0.5, 0.5); // center
