The percentage of images to be used for test can be defined by changing the variable percentage_test. We pride ourselves on high-quality, peer-reviewed code, written by an active community of volunteers. Our code is hosted on GitHub, tested on Travis CI , AppVeyor , Coveralls , Landscape and released on PyPI. 6 version for your operating system. Image warping using per-pixel flow vectors. The "add2" function in the "calc" library (which "add2vals. Python Imaging Library (PIL) The Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. Online documentation. org), creates an image average of a group of images located in directory source. warpAffine takes a 2x3 transformation matrix while cv2. Python is an interpreted, interactive, object-oriented, open-source programming language. I would like the distorted image to contain just the piece of paper, and have the five blocks be roughly the same size.
