View the original image with heatmaps

[jpatrickpark]

Hi,

Please use the load_image function in src/data_loading/loading.py to load either png or hdf5 files using appropriate view and horizontal_flip information. Alternatively, you can use read_image_mat in src/utilities/reading_images.py to load the hdf5 heatmaps without view and horizontal_flip information.

It will be loaded as a numpy array, which can be plotted as follows:

import matplotlib.pyplot as plt
from src.utilities.reading_images import read_image_mat

image = read_image_mat(image_path)
plt.imshow(image)
plt.show()

Could you clarify what you mean by that? Do you mean the image looks corrupted?

Hello, when I am trying to plot hdf5 file the image look very bad. I have used read_image_mat function. Where do I am doing the mistake. Thanks in advance.

Hello , can i save the hdf5 heatmaps to png file ?

[wooginawunan]

Sure. You could save the heat maps as png files. The generated heat maps are just numpy arrays with value between 0-1. You could use 'scipy.misc.imsave' to save it as png file but just be careful while loading those png files especially if you still want to take them as input the following models. Values might be transformed to fit the typical png image scale (0-255).

Very low res heatmap, is there anyway to clean it up? already saved as png.

@Tonthatj The heatmap is supposed to be of lower resolution than the original image. Note that the classifier is applied with a stride much bigger than 1.
