Visualizing Convnet Layers and activations

Raw data in jpeg format


jpeg converted to greyscale value integers in numpy array


integers converted to floats in numpy array


floats are between values 0.0-255.0 need to be converted to floats between 0.0-1.0


These are visualizations of the filters in Tensorflow layers


These are the visualization of the activations of the Tensorflow convolutional layers
