Tool/software:

Hi,

Wanted to perform 2D 3x3 Convolution of a 512x512 image using MMALIB only.

Input: 512x512 image (or any arbitrary size)

Kernel : 3x3 convolution filter

Output: 512x512 Convolved image.

Please provide similar samples as could not understand sample driver in

MMALIB folder (MMALIB_CNN_convolve_row_ixX_ixX_oxX_d.c).

Hello,

Please expect a response next week due to the US Thanksgiving holidays. Most of our engineers are on vacation for the long weekend.

Thanks.

Hello,

There is not currently a convolution kernel in MMALIB designed for image convolution (the kernel referenced is designed for CNN-style 2D convolution and meant to be paired with TIDL).

For now, c7x accelerated 2-D convolution is available with VXLIB (without the MMA): https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/10_00_00_05/exports/docs/vxlib_10_00_00_02/docs/user_guide/group__VXLIB__convolve.html
