Abstract:
1. A method for processing an object in a set of image data comprising: presegmenting the object into a presegmentation using a first segmentation process; analyzing the presegmentation and determining a weighting factor based on the analysis of the presegmentation; placing one or more seeds in the set of image data; segmenting by a processor of the object using a second segmentation process using the seeds and the weighting factor and the presegmentation, wherein the first and the second segmentation processes are different types of segmentation processes; and wherein the weighting factor is a function of a distance of the presegmented object from one or more seeds, wherein the weighting factor is a function of a minimum distance between presegmentation and seeds expressed as wherein the factors κ and σ are user controlled constants, γ i is the weighting factor v i and v j are nodes and d(v i , v j ) is the minimum distance from v i to all v j ε F, B with F and B being foreground and background respectively.
