Filtering and aliasing in a scene

I have 4 fisheye cameras and I project them after lens correction onto a 3D bowel mesh. I'm getting flickering or really like ants are moving in those areas of the scene (top view) of the cameras. I've tried to generate mipmaps that solved the flickering and the quality is much better. The problem is I'm running that on an embedded platform and generating mipmaps each frame is not considers and it's cpu intensive operations. Plus also getting a technique like Render to texture and do SSAA is also a problem. I have tried to create a 2D Mask where I do bicubic interpolation/filtering on those areas that the flicker appears, it didn't solve the issue. I'm looking forward for methods to solve that problem.
