I am new to OpenCV and python. I am trying to detect colors in real-time using a camera. I want to put an "if condition" when the detected color is Red, Green or Blue.

Oct 8, 2019 · I'm currently working on a project including color detection. I'm using opencv on python to do so, I can detect the color I want, i.e. blue, but I cannot manage to make the software know that this color has been detected. Here is the code I have. ` hsv_frame = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV) boundaries = [([94, 90, 45], [145, 255, 255])]

Nov 21, 2024 · bitwise_and between the image frame and mask is performed to specifically detect that particular color and discrad others. Create contour for the individual colors to display the detected colored region distinguishly. Output: Detection of the colors in real-time. Below is the implementation. Output:

Oct 11, 2019 · After color thresholding with cv2.inRange(), you will get a binary mask with any pixels within the lower and upper HSV thresholds in white. So you can simply check if white pixels exist on the mask to determine if red is present in the …

Jul 21, 2023 · First, we going to create a variable call “c”, next we will find the area of the contour with the function .contourArea (), we will pass to a conditional if in which if the value of the area is...

Jan 3, 2023 · In this article, we will discuss how to detect a monochromatic colour object using python and OpenCV. Monochromatic color means light of a single wavelength. We will use the video, captured using a webcam as input and try to detect objects of a …

Aug 4, 2014 · In this blog post I showed you how to perform color detection using OpenCV and Python. To detect colors in images, the first thing you need to do is define the upper and lower limits for your pixel values.

Feb 2, 2024 · We will use various functions from the OpenCV library for color detection. Let us discuss them below. We will detect one specific color in a given image and add boundaries around the detected segments. We need to convert the …

This instructable is used to guide with on how to extract a specific color from an image in python using openCV library. If your new to this technique then don't worry, at the end of this guide you will be able to program your very own color detection program.

Jun 18, 2024 · In this blog, we’ll explore how to perform color detection using Python and OpenCV. Before we dive into the code, make sure you have Python installed. You can install OpenCV and Numpy...
