Member Function Documentation

◆ get_patch_shape()

def visualize.PatchVisualizer.get_patch_shape	(	self,
		patch
	)

Gets the shape of a single patch.

    Basically it tries to interprete the patch as a square, and also check if it
    is in color (3 channels)

Definition at line 115 of file visualize.py.

◆ ShowChannels()

def visualize.PatchVisualizer.ShowChannels	(	self,
		patch,
		cmap = `None`,
		bg_func = `np.mean`
	)

This function shows the channels of a patch.

    The incoming patch should have shape [w, h, num_channels], and each channel
    will be visualized as a separate gray patch.

Definition at line 104 of file visualize.py.

◆ ShowImages()

def visualize.PatchVisualizer.ShowImages	(	self,
		patches,
		args,
		kwargs
	)

Similar to ShowMultiple, but always normalize the values between 0 and 1
    for better visualization of image-type data.

Definition at line 96 of file visualize.py.

◆ ShowMultiple()

def visualize.PatchVisualizer.ShowMultiple	(	self,
		patches,
		ncols = `None`,
		cmap = `None`,
		bg_func = `np.mean`
	)

Visualize multiple patches.

    In the passed in patches matrix, each row is a patch, in the shape of either
    n*n, n*n*1 or n*n*3, either in a flattened format (so patches would be a
    2-D array), or a multi-dimensional tensor. We will try our best to figure
    out automatically the patch size.

Definition at line 52 of file visualize.py.

◆ ShowSingle()

def visualize.PatchVisualizer.ShowSingle	(	self,
		patch,
		cmap = `None`
	)

Visualizes one single patch.

    The input patch could be a vector (in which case we try to infer the shape
    of the patch), a 2-D matrix, or a 3-D matrix whose 3rd dimension has 3
    channels.
