Preparing Custom Dataset for Training YOLO Object Detector

06 Oct 2019 Arun Ponnusamy

In an earlier post, we saw how to use a pre-trained YOLO model with OpenCV and Python to detect objects present in an image. (also known as running 'inference')

As the word 'pre-trained' implies, the network has already been trained with a dataset containing a certain number of classes (object categories). For example, the model we used in the previous post was trained on the COCO dataset which contains images with 80 different object categories.

YOLO Object Detection with OpenCV and Python

28 Jul 2018 Arun Ponnusamy

If you have been keeping up with the advancements in the area of object detection, you might have got used to hearing this word ‘YOLO’. It has kind of become a buzzword.

YOLO (You Only Look Once) is a method / way to do object detection. It is the algorithm /strategy behind how the code is going to detect objects in the image.

Setting up deep learning environment the easy way on macOS High Sierra

17 Feb 2018 Arun Ponnusamy

This is from a long time Ubuntu user who recently picked up a MacBook Air for all the portability it has to offer.

I am completely new to macOS. I had to look around and experiment to install all the packages I was enjoying on Ubuntu. I decided to put together a simple setup guide to get the deep learning environment (particularly for Computer Vision) up and running on macOS the easy way.
