(B)uffer (I)maging (L)ibrary, (D)irty and (E)xtendable

A library for writing procedural computer vision code in C++

• Header only No linking complications! Just copy it in your source tree.

• High C++ template use

• Define algorithms once, use them directly on several back-ends. With a mechanism based on implicit template instantiation, an algorithm is defined as a single function, and will seemlesly run several image containers such as cv::Mat, IplImage, octave arrays, numpy arrays.

Python module

import pybilde
import skimage
img = skimage.data.coins()
histogram = pybilde.lbp_features(img, 8, [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])
