Exploring Innovative Tool-kits for Semantic Image Segmentation
Written on
Introduction to Semantic Image Segmentation
Semantic image segmentation is a crucial yet challenging field within computer vision. This process involves classifying each pixel in an image into a specific category, moving beyond simple bounding boxes used in traditional object detection, as highlighted in the example below:

With semantic segmentation, image analysis becomes significantly more detailed. Its applications range from analyzing medical images to detecting lanes and areas by eliminating noisy backgrounds. This technique enables machines to interpret images with context, transforming them from mere pixel collections into meaningful representations. For a comprehensive guide on the mechanics of semantic segmentation, refer to this informative article.
Historically, before the emergence of neural networks and deep learning in the 2000s, segmentation methods relied on analyzing textures, regions, edges, graph theories, clustering, and classification techniques.
The Evolution of Segmentation with Deep Learning
The advent of deep learning has led to the development of various neural network models tailored for segmentation tasks. Below, I will share two intriguing tool-kits that are particularly useful for researchers:
- PaddleSeg

For researchers venturing into image segmentation, PaddleSeg is a highly recommended toolkit. It facilitates the creation and development of segmentation models, accelerating both the development and deployment processes. PaddleSeg is designed modularly and supports over 15 prominent segmentation networks, allowing users to customize their data enhancement techniques, backbone networks, loss functions, and other components to align with varying performance and accuracy demands.
The models included in their API comprise of DeepLabV3+, DeepLabV3, FCN, OCRNet, PSPNet, ANN, BiSeNetV2, DANet, FastSCNN, GCNet, GSCNN, HarDNet, UNet, U2Net, U2Net+, AttentionUNet, UNet++, UNet3+, DecoupledSegNet, ISANet, EMANet, and DNLNet. Furthermore, their datasets encompass Custom Dataset, Cityscapes, PascalVOC, ADE20K, and OpticDiscSeg.

For those new to the field yet eager to experiment with semantic or instance segmentation, PixelLib is an excellent option. As stated on their website, you can easily remove backgrounds from images or videos using just a few lines of code.
The two types of DeepLabV3+ models utilized for semantic segmentation within PixelLib are: - A DeepLabV3+ model with an Xception backbone trained on the ADE20K dataset, which includes 150 object classes. - A DeepLabV3+ model with an Xception backbone trained on the PascalVOC dataset, which comprises 20 object classes.
It's noteworthy that the latest version of PixelLib allows for custom training of object segmentation models using a pre-trained COCO model. The main benefit of PixelLib is its user-friendly interface, making it accessible for entry-level researchers. According to their documentation, instance or semantic segmentation can be achieved with only 5 to 7 lines of code.
Free to use: Yes.
