Hi,
I acquire a D1 frame from a camera, which should be both cropped into a CIF region of interest for image processing and displayed on screen at D1 resolution. Therefore, my idea is to capture the frame with D1 resolution, then to perform a "software" image cropping, either on ARM or DSP. Do you think is there any hardware approach to get concurrently the D1 frame and its CIF sub region?
I was looking for some already available (and optimized) function to perform this. Neither IMGLIB2 nor VLIB have such a function. Do you have any idea whether something is available?
My app is fully designed as an ARM app, and I use C6Accel + VLIB to call DSP algorithms. In case I need to design an ad-hoc cropping function, I was thinking to perform some smart and fast buffer copy. Since i'm not expert at all with the DSP side, what kind of approach could I use to speed up the copy? Typically, I call DMAI's Framecopy with SDMA enabled, but I would like to understand whether using EDMA3 on DSP would be better, or if there are other alternatives.
Thanks!
Gabriele
