Methods defined here:
- __init__(self, img, bin_fact=8L, min_range=0)
- channel_to_image(self, chan, scale_x=3, scale_y=3, y_range=64)
- Creates an iplimage displaying histogram results after its computation
- compute_histogram(self, img, bin_fact=8L, min_range=0)
- Creates the histogram of the input image
Returns a Tippy histogram, with one item by channel of input image.
The number of bins is 2^bin_fact (256 by default)
min_range is the value of the lowest bin
max_range is automatically calculated using the input image depth.
max_range = (2^img_depth)
NOTE : Supports only 8 bits images for now.
More should be added soon.
- to_images(self, scale_x=3, scale_y=3, y_range=64)
- Creates a graphical representation of an histogram.
Outputs a list of nChannels iplimages, one for each channel of the
histogram.
The images should have the same depth as the image used to create the
histogram.
- to_tables(self)
- Transforms an histogram into a list of values.
This way, it is easier to process for calculations.
Returns a list of nChannels items.
NOTE : Supports only 8 bits images for now.
More should be added soon.
