Inference

scripts.infer.imwrite(filename, img[, params]) → retval

. @brief Saves an image to a specified file. . . The function imwrite saves the image to the specified file. The image format is chosen based on the . filename extension (see cv::imread for the list of extensions). In general, only 8-bit . single-channel or 3-channel (with ‘BGR’ channel order) images . can be saved using this function, with these exceptions: . . - 16-bit unsigned (CV_16U) images can be saved in the case of PNG, JPEG 2000, and TIFF formats . - 32-bit float (CV_32F) images can be saved in PFM, TIFF, OpenEXR, and Radiance HDR formats; . 3-channel (CV_32FC3) TIFF images will be saved using the LogLuv high dynamic range encoding . (4 bytes per pixel) . - PNG images with an alpha channel can be saved using this function. To do this, create . 8-bit (or 16-bit) 4-channel image BGRA, where the alpha channel goes last. Fully transparent pixels . should have alpha set to 0, fully opaque pixels should have alpha set to 255/65535 (see the code sample below). . . If the format, depth or channel order is different, use . Mat::convertTo and cv::cvtColor to convert it before saving. Or, use the universal FileStorage I/O . functions to save the image to XML or YAML format. . . The sample below shows how to create a BGRA image and save it to a PNG file. It also demonstrates how to set custom . compression parameters: . @include snippets/imgcodecs_imwrite.cpp . @param filename Name of the file. . @param img Image to be saved. . @param params Format-specific parameters encoded as pairs (paramId_1, paramValue_1, paramId_2, paramValue_2, … .) see cv::ImwriteFlags

scripts.infer.infer_and_save_depth(*args, **kwargs)[source]

Process a single input file to produce and save visualization

Parameters

  • input_file (str) – Image file

  • output_file (str) – Output file, or folder where the output will be saved

  • model_wrapper (nn.Module) – Model wrapper used for inference

  • image_shape (Image shape) – Input image shape

  • half (bool) – use half precision (fp16)

  • save_npz (bool) – save .npz output depth maps if True, else save as png

scripts.infer.is_image(file, ext='.png', '.jpg')[source]

Check if a file is an image with certain extensions
