Simple, Otsu, and Adaptive Thresholding Implementation with Examples — One of the most commonly used segmentation techniques is thresholding. It is widely used in computer vision and is very useful to separate the object that we are interested in from the background. This article will focus on the thresholding techniques in OpenCV. There are three different types of thresholding…

Erosion, dilation, opening, closing, morphological gradient, tophat / whitehat, and blackhat explained with examples — In my last article, I wrote about some basic image processing in OpenCV. Today, we will advance a little bit and work on the morphological operations which are commonly used in image processing. Morphological operations are used to extract the region, edges, shapes, etc. What are Morphological Operations?

OpenCV for beginners: move or translate, resize, and cropping — One of the most used libraries for handling image processing and manipulation is openCV for Python users. For image classification, object detection, or optical character recognition, any work related to images in the AI world need some kind of image processing and manipulation most of the time. …

Step-by-step explanation and examples with complete code — I have several tutorials on Tensorflow where built-in loss functions and layers had always been used. But Tensorflow is a lot more dynamic than that. It allows us to write our own custom loss functions and create our own custom layers. …

With complete code — I wrote several tutorials on TensorFlow before which include models with Sequential and Functional API, Convolutional Neural Networks, Reinforcement Neural Networks, etc. In this article, we will work on a model using Functional API but it will predict two outputs with one model. If you already know how functional API…

A detailed tutorial — Pivot is a very simple function in BigQuery that can be very useful when you need to rotate rows into columns. It uses an aggregate function on rows and converts the categories in rows to columns. There is unpivot function that does totally an opposite operation. …

Adding Some Extra Flavor to Your Python Plots — Matplotlib is arguably the most popular visualization library in Python. The library is big and it is hard to really learn everything in the library. I have shared quite a lot of plots, tricks, and tips to make nicer visuals in matplotlib. …

Manual calculation from a confusion matrix and the syntax of sklearn library — Precision, recall, and f1-score are very popular metrics in the evaluation of a classification algorithm. It is very easy to calculate them using libraries or packages nowadays. But I believe it is also important to understand what is going on behind the scene to really understand the output well. If…

Linear Regression Basic, Simple, and Multiple Linear Regression Implementation in Scikit-Learn — Linear regression is the most basic type of machine learning. It is based on the simple straight-line formula we have all learned in middle school. Though there are a lot of other more complicated and efficient machine learning algorithms out there, still it is a good idea to learn the…
