IMAGE DATA PROCESSING OR GENERATION, IN GENERAL

Introduced: January 1995

Description

G06T encompasses digital image and video processing techniques applied to data acquired or created in visual form. This subclass covers fundamental computational methods for manipulating, analyzing, transforming, and synthesizing image data, including filtering, enhancement, compression, feature extraction, segmentation, and reconstruction. It addresses both the algorithmic and computational aspects of image handling across diverse domains such as medical imaging, remote sensing, computer vision, and multimedia applications. G06T excludes specialized applications of image processing that are classified in technology-specific sections (e.g., medical image analysis in A61B, document image processing in G06F), though the underlying computational techniques may be similar.

Of 19 combined children, 11 exist in both systems.

8 codes are CPC-only extensions.

Note: 8 CPC extensions are marked as secondary classification only.

1 shared codes have differing titles between IPC and CPC.
