In the previous post, we learned how to apply a fixed number of tags to images. Let’s now switch to this broader task and see how we can tackle it. In many real-life tasks, there is a ...
Funny Mirrors Using OpenCV
We all remember those awesome childhood days when we use to go to amusement parks or county fairs. One of my favorite elements of these amusement parks was the fun-house mirror room. Funny mirrors ...
t-SNE for Feature Visualization
In Machine Learning, we always want to get insights into data: like get familiar with the training samples or better understand the label distribution. To do that, we visualize the data in many ...
CNN Receptive Field Computation Using Backprop
In the previous post, we learned how to classify arbitrarily sized images and visualized the response map of the network. In Figure 1, notice that the head of the camel is almost not ...
Augmented Reality using ArUco Markers in OpenCV (C++ / Python)
In this post, we will explain what ArUco markers are and how to use them for simple augmented reality tasks using OpenCV. ArUco markers have been used for a while in augmented reality, camera pose ...
Fully Convolutional Image Classification on Arbitrary Sized Image
In this post, we will learn how to perform image classification on arbitrary sized images without using the computationally expensive sliding window approach. This post is written for people who ...
