Objects on images indexing

    July 11, 2019

    There is an enormous amount of visual information in the world. The most actual task is to find exactly what you need. Instead of Google image search, there are a lot of specific tasks with a limited number of object types for image tagging and indexing.

    Let’s look at the computer vision technologies usage example for detecting wedding accessories and classifying them, providing information on different accessories characteristics provided in the table below.

    The first step of this project is data labeling. The customer has provided a dataset of wedding photos without any labeling. And we used Amazon MTurk service to provide such.

    1. HTML template, which workers used for drawing bounding boxes and selecting the label.

    The second step was to train a neural network for category detection. We tested several neural net architectures, such as MobileNet, NasNet, ResNet, and YOLO, to find the best accuracy/speed ratio. Finally, the YOLOv2 neural net was trained on the labeled dataset.

    The third step was to train an ensemble of models to make a classification of detected categories by tags. We used PyTorch pre-trained vgg16 models to train it on a labeled dataset.

    The demonstrated approach may be used in eCommerce to automate image tagging. It’s also applicable for quick searches of goods with similar characteristics.
