工程师们好，
想问下能不能更换drp库函数中的结构元大小，默认3*3的有点太小了，多进行几次的话时延有点长，还是说不能修改只能用opencv去实现了
目前这两个库的参数是固定死的不能修改。只能多做几次，例如：
void R_BCD_DRP_Dilate(uint32_t input_address, uint32_t output_address1, uint32_t output_address2, uint32_t input_width, uint32_t input_height, uint8_t times)
{
int32_t ret_val;
uint32_t tile_no;
uint8_t loop;
if(times == 0)
return;
}
