You can use field `user_block_size` to set specific block size for :ocv:func:`gpu::convolve` function. If you leave its default value `Size(0,0)` then automatic estimation of block size will be used (which is optimized for speed). By varying `user_block_size` you can reduce memory requirements at the cost of speed.
:param src: Source image. Only ``CV_8UC1`` images are supported for now.
:param sqsum: Squared integral image containing 64-bit unsigned integer values packed into ``CV_64FC1`` .
:param stream: Stream for the asynchronous version.
:param user_block_size: Block size. If you leave default value `Size(0,0)` then automatic estimation of block size will be used (which is optimized for speed). By varying `user_block_size` you can reduce memory requirements at the cost of speed.
