hi_remap_lut

Description

Defines the information about the pixel position remapping LUT.

Prototype

 typedef struct {
    hi_u32 src_pic_width;
    hi_u32 src_pic_height;
    hi_u32 dest_pic_width;
    hi_u32 dest_pic_height;
    hi_void *lut;
    hi_u32 lut_size;
    hi_u64 reserved;
} hi_remap_lut;

Members

The resolution of the input and output images ranges from 10 x 6 to 4096 x 8192.

Member	Description
src_pic_width	Input image width.
src_pic_height	Input image height.
dest_pic_width	Output image width.
dest_pic_height	Output image height.
lut_size	Memory size of the pixel position remapping LUT, in bytes. You can call the hi_mpi_vpc_get_lut_mem_size interface to obtain the memory size.
lut	Pointer to the memory address of the pixel position remapping LUT. The memory needs to be allocated by calling the hi_mpi_dvpp_malloc API in advance.
reserved	Reserved. To ensure compatibility in later versions, use the memset struct for resetting and initialization. Do not explicitly access the reserved field in the code.
