Convert Color Space with cv2.cvtcolor

Tutorial

The cv2.cvtcolor method allows you to convert the color space of an image. For example, you can convert an image from RGB to BGR, BR to greyscale, BGR to HSV, and more.

The cvtcolor method accepts an image and a property that specifies the conversion you want to apply. The method then returns an object that has been updated using the specified transformation.

Here are a few examples of color scape conversions with OpenCV:


image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB) # convert BGR to RGB

image = cv2.cvtColor(image, cv2.COLOR_BGR2HSV) # convert BGR to HSV

Next Steps

OpenCV can be used with the open source supervision Python package.

supervision provides an extensive range of functionalities for working with computer vision models. With supervision, you can:

1. Process and filter detections and segmentation masks from a range of popular models (YOLOv5, Ultralytics YOLOv8, MMDetection, and more).
2. Process and filter classifications.
3. Compute confusion matrices.

And more! To learn about the full range of functionality in supervision, check out the supervision documentation.
