Gabor texture analysis effectively extracts features from liver CT images for content-based image retrieval. This method aids in identifying various CT findings, improving diagnostic capabilities.

Area of Science:

  • Medical Imaging
  • Computer Vision
  • Biomedical Engineering

Background:

  • Gabor schemes are successful in texture analysis due to Gabor elementary functions (GEF's) resembling wavelet primitives in image representation.
  • Liver CT image analysis requires robust texture feature extraction for accurate interpretation of pathologies.

Purpose of the Study:

  • To apply the Gabor approach for analyzing liver CT image textures.
  • To extract feature vectors from liver CT images using Gabor methods.
  • To utilize these feature vectors for content-based image retrieval (CBIR) of liver CT scans.

Main Methods:

  • Utilized Gabor schemes for image representation and texture analysis.
  • Extracted feature vectors from liver CT images.
  • Implemented a content-based image retrieval system using the extracted Gabor texture features.
