Object detection is one of the most exciting problems in computer vision. It involves identifying and localizing multiple objects within an image. Over the years, I’ve worked extensively with Python Keras to build robust object detection models, and RetinaNet has always stood out for its balance between speed and accuracy. RetinaNet is a single-stage detector … Read more >>
Image segmentation is a crucial task in computer vision, where the goal is to classify each pixel in an image into meaningful categories. Over the years, fully-convolutional networks (FCNs) have become the go-to architecture for this task. With over four years of experience working with Python and Keras, I’ve found composable FCNs to be a … Read more >>
Image segmentation is a critical task in computer vision where we classify each pixel of an image to identify objects or boundaries precisely. During my years working with Keras, I found BASNet (Boundary-Aware Salient Object Detection Network) to be one of the most effective architectures for segmenting fine boundaries in images. In this tutorial, I … Read more >>
Semantic segmentation is a vital task in computer vision, where the goal is to classify each pixel in an image into a category. Over the years, DeepLab models have become a popular choice for this due to their accuracy and efficiency. In this tutorial, I’ll share my firsthand experience working with DeepLabV3+ in Keras to … Read more >>
Image segmentation is one of the most exciting tasks in computer vision. It involves classifying each pixel in an image to identify objects or regions of interest. I have worked on various image processing projects using Python, and one architecture that consistently stands out for segmentation tasks is the U-Net. U-Net was originally designed for … Read more >>
Image classification is a fundamental task in computer vision. Over the years, transfer learning has become a popular approach to improve model performance without needing massive datasets. One of the most powerful transfer learning methods is BigTransfer (BiT). I’ve worked extensively with Python Keras, and in this article, I’ll walk you through how to use … Read more >>
When I first started working with Python over a decade ago, understanding the nuances of its built-in data structures was a game-changer. Among these, the Python set is an incredibly useful tool for handling unique collections of items. However, one common question I often encounter is: How do you create an empty set in Python? … Read more >>
As an experienced Python developer, I’ve often encountered situations where designing clean, maintainable, and scalable code becomes challenging. One concept that has helped me immensely is the use of interfaces in Python. If you’re coming from languages like Java or C#, you might be familiar with interfaces as a way to enforce certain methods in … Read more >>
As a Python developer with over a decade of experience, I’ve encountered many situations where I needed to check if multiple conditions were false before proceeding. Checking if both variables are false in Python is a common task, especially when working with flags, user inputs, or managing program flow. Even though it sounds simple, there … Read more >>
I’ve often needed to verify if a variable is not null before proceeding with operations. This check is fundamental when working with data, user inputs, or APIs because null values can cause your program to crash or behave unexpectedly. In Python, the concept of “null” is represented by the special value None. Knowing how to … Read more >>
