Similus allows you to easily compute the similarity between 2 images
- Grayscale Image Comparison
- Caching of internals for fast comparison of one to many
- Rudimentary OCR
>>> import Image
>>> import similus
>>> im1, im2, im3 = Image.open('im1.jpg'), Image.open('im2.jpg'), Image.open('im3.jpg')
>>> similus.compare(im1, im2)
212.231
>>> similus.compare(im2, im3)
123.321>>> im3 = Image.open('im3.jpg')
>>> crab = similus.Crab([im1])
>>> crab.add(im2)
>>> 'compare im3 to im1 and im2'
>>> crab.similarities(im3)
((im2, 232.3311), (im1, 193.1231))
>>> len(crab)
2
>>> crab.clear()
>>> len(crab)
0If you have the font and can crop to single words (or even better single characters), Otter will automatically create images and perform image similarity comparisons
>>> import string
>>> alphabet = string.letters + string.digits
>>> otter = similus.Otter()
>>> otter.create_images('fonts/arial.ttf', alphabet=alphabet, directory='similus_images')
>>> otter.ocr(im1)
u'Shake dat booty'
>>> 'We can load images after the fact'
>>> otter = None
>>> otter = similus.Otter(directory='similus_images')
>>> otter.ocr(im1)
u'Shake dat booty'
>>> otter.ocr_char(im1.crop((0,0,10,12)))
