In OpenCv module, we can use the function cv2.imread() to read an image. When inputting the image path, the image should be in the working directory or a full path of image should be given. cv2.IMREAD_COLOR − This function loads a color image and any transparency of image will be ... Read More

This is a method in image processing to do contrast adjustment using the image's histogram. Actually this method usually increases the global contrast of many images, especially when the usable data of the image is represented by close contrast values and through this adjustment, the intensities can be better distributed ...

We know that when we solve any image related problem, we have to take a matrix. The matrix content will vary depending upon the image type - either it would be a binary image(0, 1), gray scale image(0-255) or RGB image(255 255 255). So if we want to add of ... Read More

The photomosaic is a technique, where we can split our image into a grid of squares. Each square will be replaced by some other images or colors. So when we want to see the actual image from a certain distance, we can see the actual image, but if we come ... Read More
