Morphological operations are used to extract image components that are useful in the representation and description of region shape. Morphological operations are some basic tasks… Read More
Translation refers to the rectilinear shift of an object i.e. an image from one location to another. If we know the amount of shift in… Read More
Image Pyramids are one of the most beautiful concept of image processing.Normally, we work with images with default resolution but many times we need to… Read More
To identify circles, ellipses, or in general, any shape in which the pixels are connected we use the SimpleBlobDetector() function of OpenCV. In non-technical terms,… Read More
Thresholding is a technique in OpenCV, which is the assignment of pixel values in relation to the threshold value provided. In thresholding, each pixel value… Read More
Prerequisite: Simple Thresholding using OpenCV In the previous post, Simple Thresholding was explained with different types of thresholding techniques. Another Thresholding technique is Adaptive Thresholding.… Read More
Color spaces are a way to represent the color channels present in the image that gives the image that particular hue. There are several different… Read More
Image resizing refers to the scaling of images. Scaling comes in handy in many image processing as well as machine learning applications. It helps in… Read More
Contours are defined as the line joining all the points along the boundary of an image that are having the same intensity. Contours come handy… Read More
Prerequisite: Arithmetic Operations on Images using OpenCV | Basics We can perform different Arithmetic operations on images e.g. Addition, Subtraction, etc. This is possible because… Read More
Image Blurring refers to making the image less clear or distinct. It is done with the help of various low pass filter kernels. Advantages of… Read More
Template matching is an image processing technique which is used to find the location of small-parts/template of a large image. This technique is widely used… Read More
Grayscaling is the process of converting an image from other color spaces e.g. RGB, CMYK, HSV, etc. to shades of gray. It varies between complete… Read More
As we know OpenCV is a widely used library for image processing. It provides a wide sense of image processing. Let’s see how to create… Read More
