Function mindspore::dataset::ResizeBilinear

Function Documentation

bool mindspore::dataset::ResizeBilinear(const LiteMat &src, LiteMat &dst, int dst_w, int dst_h)

resizing image by bilinear algorithm, the data type of currently only supports is uint8, the channel of currently supports is 3 and 1.

Parameters

  • src – [in] Input image data.

  • dst – [in] Output image data.

  • dst_w – [in] The width of the output image.

  • dst_h – [in] The length of the output image.

Returns

Return true if transform successfully.

Example
/* Assume p_rgb is a pointer that points to an image with shape (width, height, channel) */
LiteMat lite_mat_src(width, height, channel, (void *)p_rgb, LDataType::UINT8);
LiteMat lite_mat_dst;

/* Resize to (256, 256, 3) */
ResizeBilinear(lite_mat_src, lite_mat_dst, 256, 256);
std::cout << lite_mat_dst.width_ << " " << lite_mat_dst.height_ << " " << lite_mat_dst.channel_ << std::endl;
