Description
TomoSegMem is a software suite intended to assist users in segmenting membranes in tomograms. It is based on a local differential structure approach and on a Gaussian-like model of membrane profile. The approach is composed of a number of sequential stages. First, it isolates information through scale-space and finds potential membrane-like points at a local scale. Then, the structural information is integrated at a global scale to yield the definite segmentation. Code optimization and multithreading techniques have been used in the implementation in order to reduce the processing time and memory consumption. Additional programs are provided to convert the segmentation results to formats directly acceptable by well-known tools like Amira and IMOD. This allows the users to supervise and edit the segmentation results as necessary with their favourite visualization tools.
A detailed description of the procedure implemented in the package can be found in the following article:
