Function Usage

Image resizing function. Before calling this API, call Init to initialize this function.

• Supported image formats of the input/output data:
  • Atlas 200/300/500 inference product: YUV_SP_420 and YVU_SP_420 (nv12 and nv21).
  • Atlas 200I/500 A2 inference product: supports YUV_SP_420 and YVU_SP_420 (nv12 and nv21).
  • Atlas inference product: YUV_SP_420, YVU_SP_420, RGB_888 and BGR_888 (nv12, nv21, rgb, and bgr). The resolution of the RGB (BGR) image format cannot exceed 4096 x 4096.
• inputDataInfo: The actual image resolution range is [18 x 6, 4096 x 4096]. The size of YUV_SP_420 or YVU_SP_420 image can reach 8192 x 8192.
• resize: Its maximum resolution is 4096 x 4096, and the minimum resolution is 32 x 6.
• outputImage: The width is automatically aligned by 16, and the height is automatically aligned by 2. So the size range is [32 x 6, 4096 x 4096].
• The width and height of the resized image is a multiple of [1/32, 16] of the actual width and height range.
