This article will help you to work with OpenCV & Python and with the help of that how you can convert the image into grayscale using Odinub. OpenCV is a Library which is used to carry out image processing using programming languages like Python. In this tutorial we will check how to read an image and how to convert that color image into grayscale.
Step 1: Install OpenCVIf you haven’t yet install OpenCV then Install first OpenCV.
You can add after normalize cout.
Starting with OpenCV 3.0, there is yet another convention. Conversion codes are embedded in the namespace cv:: and are prefixed with COLOR. As far as I have seen, the included file path hasn't changed (this is not a typo). Thanks, I'll update the answer. May be helpful for late comers. In order to convert a color image to Grayscale image using OpenCV, we read the image into BufferedImage and convert it into Mat Object. Its syntax is given below: File input = new File('digitalimageprocessing.jpg'); BufferedImage image = ImageIO.read(input); //convert Buffered Image to Mat.
