Dec 03, 2012 · I did not fully understand how to read the OpenCV API documentation and instead of demonstrating how to capture an image with OpenCV 2, I just demonstrated a way to capture an image with OpenCV 1.x in a way different from the example I first followed. Here is how one would actually use the newer, OO, consolidated OpenCV 2 Python API.
I am trying to apply fisheye effect on a normal image using opencv-fisheye module. For converting a fisheye image to normal image, 'cv2.fisheye.undistortimage' api can be used. I am not sure how to get the fisheye image with the help of 'cv2.fisheye.distortPoints' function. Any working sample code/algorithm is much appreciated.

Jan 05, 2016 · Using OpenCV and Python, an RGB color image can be converted into a cartoon in five steps: Apply a bilateral filter to reduce the color palette of the image. Convert the original color image to grayscale. Apply a median blur to reduce image noise in the grayscale image. Create an edge mask from the grayscale image using adaptive thresholding.
Aug 30, 2015 · OpenCV (open source computer vision) is released under a BSD license and hence it’s free for both academic and commercial use. It has C++, C, Python and Java interfaces and supports Ubuntu Linux. OpenCV was designed for computational efficiency and with a strong focus on real-time applications.
