摘要
The present invention is a set of algorithms or calculations that may be applied to efficiently use atlas-based segmentation using QBinary (binary and/or quasi-binary) representations of images and/or their ROIs. A QBinary representation of an image or a part of an image (for example, such as a ROI) may be a binary image (for example, such as a code with 1 bit) and or a quasi-binary image (for example, such as a code with more than 1 and less than 8 bits) that serves to represent that image and/or ROI in an atlas. Two-dimensional QBinary codes may be used to both construct QBinary atlases and QBinary-controlled atlases with or without QB-Codes registration. Additionally, the present invention may offer a set of algorithms to sequentially auto-contour (or auto- segment) individual slices of a volume set of digital images without or without QB-Codes registration, provided one slice is semi-automatically contoured by a human operator.
