This topic demonstrates how to run Super Resolution demo application, which reconstructs the high resolution image from the original low resolution one. You can use the following pre-trained model with the demo:
single-image-super-resolution-1033
, which is the primary and only model that performs super resolution 4x upscale on a 200x200 imageFor more information about the pre-trained models, refer to the https://github.com/opencv/open_model_zoo/blob/master/intel_models/index.md "Open Model Zoo" repository on GitHub*.
On the start-up, the application reads command-line parameters and loads the specified network. After that, the application reads a 200x200 input image and performs 4x upscale using super resolution.
NOTE: By default, Inference Engine samples and demos expect input with BGR channels order. If you trained your model to work with RGB order, you need to manually rearrange the default channels order in the sample or demo application or reconvert your model using the Model Optimizer tool with
--reverse_input_channels
argument specified. For more information about the argument, refer to When to Specify Input Shapes section of Converting a Model Using General Conversion Parameters.
Running the application with the -h
option yields the following usage message:
Running the application with the empty list of options yields the usage message given above and an error message.
To run the sample, you can use public or pre-trained models. To download the pre-trained models, use the OpenVINO Model Downloader or go to https://download.01.org/opencv/.
NOTE: Before running the sample with a trained model, make sure the model is converted to the Inference Engine format (*.xml + *.bin) using the Model Optimizer tool.
To do inference on CPU using a trained model, run the following command:
The application outputs a reconstructed high-resolution image and saves it in the current working directory as *.bmp
file with sr
prefix.
