OpenCV文档不完整

唯一的医生 hall::filter2d 我能找到的是 here . 不完全正确 Filter2D 但我认为参数的简短解释可能会对你有所帮助。

/**
   @brief hal_filterInit
   @param context double pointer to user-defined context
   @param kernel_data pointer to kernel data
   @param kernel_step kernel step
   @param kernel_type kernel type (CV_8U, ...)
   @param kernel_width kernel width
   @param kernel_height kernel height
   @param max_width max possible image width, can be used to allocate working buffers
   @param max_height max possible image height
   @param src_type source image type
   @param dst_type destination image type
   @param borderType border processing mode (CV_HAL_BORDER_REFLECT, ...)
   @param delta added to pixel values
   @param anchor_x relative X position of center point within the kernel
   @param anchor_y relative Y position of center point within the kernel
   @param allowSubmatrix indicates whether the submatrices will be allowed as source image
   @param allowInplace indicates whether the inplace operation will be possible
