So, in today’s blog of this OpenCV series, we are going to generate a negative image. Talking about negatives, it’s a very nostalgic feeling because nowadays we are not used to seeing negatives but about 10-15 years ago, first of…

In today’s blog of this OpenCV series, we are going to implement a Laplacian High Pass Filter or Laplacian 2nd order derivative for images which is a very useful image processing mostly used in defense domains (in missiles or tanks)…

In today’s very short blog we will see that how we can plot a histogram of a grayscale image. The first way is using NumPy and the second way is using matplotlib. This is going to be a very interesting…

In this blog what we will be seeing will not be something less than magic. You will be amazed after watching the power of Median Blur. So without any further due, let’s do it. Step 1 – Import all the…

So, in today’s blog, we will see that how we can perform morphological operations like erosion, dilation, and gradient upon an image to enhance it. Morphological transformations are some simple operations based on the image shape. It is normally performed…

In today’s blog, we will see that how we can detect contours in an image using the cv2 module. Contouring is a very useful operation when our use case involves geological terrain images or studying weather maps, etc. This is…

In this very short blog, we will see that how we can plot all 3 color channels histogram (red, green, blue) of an Image in Python using OpenCV. This is going to be a very interesting blog, so without any…

In today’s blog, we will see how to perform the most famous 4 types of Blurrings in cv2 (Simple Blur, Box Blur, Gaussian Blur, and Median Blur). This is going to be a very interesting blog, so without any further…

In this blog, we will be creating a BGR Palette in OpenCV that will change its color live according to our actions on the track bar. Didn’t get that?? Check out the video here – Sneak at our Result……

While playing with images in OpenCV we can do various fun stuff using its inbuilt functions. One of them is drawing basic shapes like circles, rectangles, ellipses, and lines on images. In today’s very short blog we will see that…
