ImageTensorGenerator

The ImageTensorGenerator is a program for pre-processing a .jpg image before generating a .raw tensor file from it.

Build option: To build ModelAccuracyTool, pass the following options to Cmake:

  • -DBUILD_ACCURACY_TOOL=1
Cmd:
-h –help Display help messages
-f –model-format Format of the intended model file that uses the images.Different formats have different image normalization styles.Accepted values (tflite)
-i –infile Input image file to generate tensor from
-o –outfile Output raw tensor file path
-z –output-type The data type of the output tensors.If unset, defaults to "float" for all defined inputs. Accepted values (float, int or qasymm8)
–new-width Resize image to new width. Keep original width if unspecified
–new-height Resize image to new height. Keep original height if unspecified
-l –layout Output data layout, "NHWC" or "NCHW". Default value: NHWC

Example usage:
./ImageTensorGenerator -i /path/to/image/dog.jpg -o /output/path/dog.raw –new-width 224 –new-height 224
