OpenCV Error: Insufficient memory

Question

OpenCV Error: Insufficient memory (Failed to allocate 76800 bytes) in OutOfMemoryError, file ../core/src/alloc.cpp, line 52 
 I'm getting this error when i run my open cv code for an hour.Is there any way to fix this without reducing image resolution.

It occurs well with GR-LYCHEE (3MB RAM). 
 
Did you see the following example ?

When you use some static image buffers like RGB, HSV and gray, you may use the area of "NC_BSS" like below. 
 
uint8_t hsv_buf[3 * IMAGE_HW * IMAGE_VW]__attribute((section("NC_BSS"),aligned(32))); 
 
Mat img_hsv(IMAGE_VW, IMAGE_HW, CV_8UC3, hsv_buf);
