android - Using a Lookup Table (PNG) to modify an Image -
in ios application utilize lookup tables (colorlut believe) modify/add filter image. works + super fast. 1 of tables shown below.
the question is - how can accomplish same effect through android? know project phone call jh labs, should contain lookup feature, i'm not sure on how utilize i'm unable pass of table png file on ios (via gpuimagelookupfilter). need convert somehow first, or how do it?
so while it's not total answer, think looking renderscript. there few predone filter operations called intrinsics (more info on them here).
applying of basics of renderscript, allow take image , compile allocation. allows send parallel processors on device , perform per unit memory operations on them. there issues mechanism beingness available/compatible across os versions, seems more stable in years past. graphics oriented, , more of general computation framework can purposed general graphics operations.
