各位好，
VLIB_grayscale_morphology函数调用，假如我要对一个256x256 8位灰度图像做开运算，模板3x3元素均为1.
那么该如何设置下列参数？
blk_w是256？还是图像需要加上边界，成为258
line_ofst 是256？如何理解offset between input lines这句话？
blk_h 是3？
refl_se_ptr[]是什么？Reflected structuring element data pointer有什么物理意义？
scratch1_ptr与scratch2_ptr有何区别？
void VLIB_grayscale_morphology
(
uint16_t blk_w, //width of input block, in elements (UQ16.0)
uint16_t line_ofst, //offset between input lines, in elements (UQ16.0)
uint16_t blk_h, //height of input block (UQ16.0)
const uint8_t data_ptr[], //input data pointer (UQ8.0)
uint16_t se_w, //width of structuring element block, in elements (UQ16.0)
uint16_t se_h, //height of structuring element block (UQ16.0)
const uint8_t se_ptr[], //structuring element data pointer (UQ8.0)
const uint8_t refl_se_ptr[], //Reflected structuring element data pointer (UQ8.0)
uint8_t scratch1_ptr[], //scratch 1 pointer. Size of this scratch buffer should be equal to input image size (UQ8.0)
uint8_t scratch2_ptr[], //scratch 2 pointer. This scratch buffer is for temproray data storage and it is used only when se_h =1,
//and all the elements of structuring element is one and (blk_h - (se_h-1))se_h = 0. Size of this buffer should be 32*se_h (UQ8.0)
uint8_t output_ptr[], //output data pointer (UQ8.0)
uint8_t operation //Operation selection
);
忍不住说几句TI的库--“严谨有余，灵活不足，晦涩难懂”,每个函数为什么不能给个使用例子？
