CGEImageHandler takes more memory and time to create filtered bitmap

[ManojCSE90]

Hi i have checked that CGEImageHandler takes more memory and time to create filtered bitmap in Background.

When i use ImageGLSurfaceView and apply filter it takes very less memory and time also.

e.g. to process 46 LUT filter using CGEImageHandler
memory uses = 400MB to 500MB
time= 5 min to 7 min

same thing if i process filter using ImageGLSurfaceView
memory uses = 150MB to 180MB
time = 43 second

can you suggest the better option to create filtered Bitmap in background without using ImageGLSurfaceView (UI) and which takes less memory and time
