what are the Image processing techniques supported by Mali-400 ?

Hi Rich,

Thanks for your reply, we are not finalized with post processing of the image, but it can include "lens distortion",  "Image Filtering", "Pixel Shading", etc.

Do you have any link/sorce/doc that captured all the Image processing techniques supported in OpenGL-Es-2.0  or on top of it?

Our major concern was, whether  it is possible for Mali-400 do pixel processing on the Live video on the camera, from your reply its cleared YES.

Thanks

Hi Ravinder,

Mali-400 can do whatever you program it to do .

There are lots of examples, libraries and blogs on how to use OpenGLES to perform image processing using programmable shaders, for example: GLImageProcessing/GLImageProcessing at master · twenty3/GLImageProcessing · GitHub, yulu/GLtext · GitHub, OpenGL ES Pixel Shaders Tutorial - Ray Wenderlich.

There are also many examples for image processing using desktop OpenGL shaders which, while they won't directly, you can use as inspiration for the image processing techniques themselves.

With regards to processing video, the video is just a sequence of frames which you can process one at a time.  Providing your image processing is fast enough that it can complete processing a frame before your next video frame arrives then you can of course do processing on a live video feed in real time.

Hope this helps,

Rich

Thanks Rich,

This cleared my understanding is correct. the links shared are most useful.
