![]() As discussed in earlier articles on labeling tools for computer vision and NLP, there are many commercial or open-source solutions available for the labeling process, all with their advantages and disadvantages. Now, if your use case does not entail a conveniently labeled dataset such as the ubiquitous imagenet, manual labeling work is necessary before we can even start to train a machine learning model. As with all supervised learning techniques, it is necessary to feed the training loop with labeled data for the algorithm to be able to pick up patterns in the images. Real contexts in which we have encountered image classification problems are, for instance, the extraction of information from technical drawings, the automatic attribution of detected defects, or the visual inspection of the success of a manufacturing process in one of our ongoing projects. Of course, applications will not always be as mundane as telling hotdogs from other foods, but this simple case makes a good graphic example for illustrating what we are after. Image classification is one of the most fundamental applications of machine learning to computer vision. Image classification and the need for yet another labeling tool ![]() ![]() That is exactly right and also what we set out to do in this article: Create a simple annotation tool to easily assign class labels to a set of images. Wouldn't it be great if there was a streamlined solution that makes this labeling process more efficient, even fun? However, such a heavy-handed approach sounds rather tedious and is likely prone to fat-fingering errors. One way to do that would be to open up one image at a time and keep track of image classes in another file, e.g., a spreadsheet. That is, we sometimes have to manually look at hundreds or even thousands of images that do or do not contain hotdogs, and decide if they do. To be able to address this or a similarly important question by means of a machine learning model, we first need to come up with a labeled dataset for training. Once complete, you can click Close to close the File Manager window.'Hotdog' or 'not hotdog'?
