*        2- In the vx_imagepatch_addressing_t structures of the 'addr[]' parameter
*          2.1- Only dim_x, dim_y, stride_x and stride_y fields must be provided by the application. Other fields (step_x, step_y, scale_x & scale_y) are ignored by the vxCreateImageFromHandle function.
*          2.2- the layout of the imported memory must follow a row-major order. In other words, stride_x should be sufficiently large so that there is no overlap between data elements corresponding to different pixels, and stride_y >= stride_x * dim_x.
