Defining Semantic Segmentation

Semantic segmentation classifies image areas by assigning a class to selected regions. Instances of a class are grouped based on class membership, not individually distinguished. The output is commonly a PNG mask with distinct colors representing each class.

Where is Semantic Segmentation Commonly Applied?

Applications of Semantic Segmentation:

Medical: Map entire DICOM slices of organs for detailed medical imaging.

Geospatial: Monitor deforestation or urbanization areas on satellite imagery for environmental analysis.

Automotive: Identify every element in a road scene for advanced driver-assistance systems.

Industrial: Segment casting defects on metallic parts for quality control in manufacturing.

Agriculture: Distinguish crops from weeds to optimize herbicide usage for precision farming.

Retail: Create virtual dressing rooms that distinguish users from the background for an enhanced shopping experience.

Advantages & Disadvantages

Advantages:

  1. Ultra-Precise Labeling:

    • Achieves unparalleled precision as every pixel is meticulously assigned to a specific class, providing detailed and accurate segmentation.

  2. Advancements in Automation:

    • Recent innovations in labeling automation, including superpixel, domain-agnostic, or domain-specific smart segmentation, have significantly accelerated the annotation process.

Disadvantages:

  1. Time-Consuming Manual Segmentation:

    • Manual segmentation, even with the assistance of smart tools, can be time-consuming, affecting the overall efficiency of the annotation process.

  2. Limitation in Identifying Instances and Overlaps:

    • While semantic segmentation identifies categories in the image, it doesn’t specify the number of instances or how they overlap, limiting the depth of information provided.

Semantic Segmentation Guidelines

  1. Choosing the Right Tool for Manual Segmentation:

    • Opt for tools that offer flexibility in changing the shape and size of brushes, but consider using polygons for achieving higher precision in manual semantic segmentation.

  2. Precision with Polygons:

    • While tools may provide features for brushes, polygons often result in higher precision during the manual segmentation process.

  3. Consider Instance Segmentation for Quantity Information:

    • For scenes where knowing the quantity of a specific object is crucial, instance (or “instance-aware”) segmentation is more appropriate. It assigns a unique class and color to each individual instance, providing detailed quantity information.

  4. Enhanced Segmentation for Adjacent Objects:

    • Some tools allow drawing on top of or underneath existing masks to facilitate segmentation of adjacent objects. This ensures no missed pixels in-between, making it easier to draw the second mask
