How can we implement semantic segmentation using deep learning?

In order to perform semantic segmentation, a higher level understanding of the image is required. The algorithm should figure out the objects present and also the pixels which correspond to the object. Semantic segmentation is one of the essential tasks for complete scene understanding.

What is image segmentation deep learning?

Image segmentation is the task of clustering parts of an image together that belong to the same object class. This process is also called pixel-level classification. In other words, it involves partitioning images (or video frames) into multiple segments or objects.

What does an image segmentation model expect as an input?

Image segmentation typically generates a label image the same size as the input whose pixels are color-coded according to their classes. Figure 4 shows an example that segments four different classes in a single image: table, chair, sofa and potted-plant.

How is semantic segmentation done?

Semantic segmentation is the task of assigning a class to every pixel in a given image. Note here that this is significantly different from classification. Classification assigns a single class to the whole image whereas semantic segmentation classifies every pixel of the image to one of the classes.

Why do we do semantic segmentation?

More specifically, the goal of semantic image segmentation is to label each pixel of an image with a corresponding class of what is being represented. Because we’re predicting for every pixel in the image, this task is commonly referred to as dense prediction.

What is semantic segmentation used for?

Semantic Segmentation is a technique that enables us to differentiate different objects in an image. It can be considered an image classification task at a pixel level.

How do you train semantic segmentation?

The steps for training a semantic segmentation network are as follows:

  1. Analyze Training Data for Semantic Segmentation.
  2. Create a Semantic Segmentation Network.
  3. Train A Semantic Segmentation Network.
  4. Evaluate and Inspect the Results of Semantic Segmentation.
