I am new to using jit.gl.pix and I was wondering if there is a way to apply an effect (like color mapping) to only a part of the texture/matrix, preferably with a blur around the edges.

The idea is to use params to specify the boundaries of this sub-texture/matrix

Also if someone else knows another efficient way outside of jit.gl.pix to do this I am all ears!

Any help in the right direction is appreciated!

the typical way of doing this is to composite your clean and dirty image stream together using an alpha channel. a rectangular alpha shape with blended edges is quite easy with the built-in edgeblend shader (tr.edgeblend.jxs), other shapes require some different techniques. the patch below shows the edgeblend technique and one that capture a gridshape to a texture, blurs it, and uses it as the alpha channel.

Thank you Ramirez! This helped me a lot! I will fiddle with both options to see which one works the best for my needs and performance wise.
