AI Researchers Develop A Computer Vision Method For Highly Accurate Dichotomous Image Segmentation

Since many years ago, computer vision datasets that are the basis for many Artificial Intelligence (AI) models have provided accurate annotations. They have been good enough to meet the needs of perceiving machine systems. However, to enable sensitive human-machine interaction and immersive virtual life, AI has reached an era when it demands exact outputs from computer vision algorithms. One of the most fundamental computer vision techniques, image segmentation, is essential for helping robots perceive and comprehend the outside world.

For various applications, including image editing, 3D reconstruction, augmented reality (AR), satellite image analysis, medical image processing, and robot manipulation, it can offer more accurate descriptions of the targets than image categorization and object identification. Based on how the applications mentioned above directly influence physical things, we may classify them as “light” (such as picture editing and image analysis) and “heavy” (such as manufacturing and surgical robots).

The “light” applications may tolerate segmentation failures and deflects to a greater extent since these problems primarily increase labor and time expenses, often within reason. In contrast, deflects or failures in “heavy” applications are more likely to result in catastrophic repercussions, such as physical harm to objects or injuries that can be lethal to beings like people and animals. As a result, the models for these applications must be exact and reliable. Due to accuracy and robustness, most segmentation models are still less appropriate in such “heavy” applications, which prevents segmentation approaches from playing increasingly crucial roles in broader applications.

Researchers refer to this job as dichotomous image segmentation (DIS), which tries to separate extremely accurate items from nature photographs. They aim to handle the “heavy” and “light” applications in a universal framework. Existing picture segmentation challenges, however, mainly concentrate on segmenting objects with particular qualities, such as conspicuous, disguised, meticulous, or specific categories. Since most of them utilize the same input/output formats and seldom ever employ exclusive techniques explicitly made for segmenting targets in their models, practically all jobs depend on the dataset.

In contrast to semantic segmentation, the suggested DIS task often concentrates on pictures with one or more targets. It is easier to obtain fuller, more precise information about each target. As a result, it is very encouraging to develop a category-agnostic DIS task for precisely segmenting objects with various structural complexity, regardless of their properties.

Researchers put forth the following novel contributions:

  1. 5,470 high-resolution photos and exact binary segmentation masks are combined in DIS5K, a large, extendible DIS dataset
  2. A unique starting point, IS-Net, designed with intermediate supervision, avoids over-fitting in high-dimensional feature spaces by requiring direct feature synchronization.
  3. A newly developed human correction efforts (HCE) metric counts the human interventions required to fix the wrong areas. 
  4. DIS benchmark is based on the latest DIS5K, making this the most comprehensive DIS analysis

The dataset is set to be released soon along with the model on the GitHub repo mentioned below.
