The invention relates to a method of segmenting an image of a structure stored as a set of spatially related data points representing variations in a predetermined parameter, said method comprising the steps of selecting a seed point within the structure to be segmented, assigning to each of the data points a value of connectivity indicative of the confidence that respective areas of the data points are part of the same structure as said see point, said value of connectivity including a function of the distance of the respective point from said seed point, establishing a threshold value for said level of connectivity and selecting for display data points meeting said threshold value.
A method of segmenting an image of a structure stored as a set of spatially related data points representing variations in a predetermined parameter, said method comprising the steps of selecting an initial location within the structure to be segmented, assigning to each of the data points a value of connectivity indicative of the confidence that respective ones of the data points are part of the same structure as said initial location, said value of connectivity including a function of the distance of the respective point from said initial location, establishing a threshold value for said value of connectivity and selecting for display data points meeting said threshold value.
An imaging apparatus comprising a data store having a set of spatially related data points representing variations in a predetermined parameter, a comparator to compare a value of said predetermined parameter at said point with that of an initial location and distance of said point from said initial location and establish a value of connectivity indicative of the confidence that respective ones of said data points are part of the same structure, and a selector to select respective points that meet an established threshold.
A method of segmenting an image of a structure stored as a set of spatially related data points representing variations in a predetermined parameter, said method comprising the steps of selecting said initial location from an examination of a data set of said structure to identify particular characteristics of said structure.
A method of segmenting an image of a structure stored as a set of spatially related data points representing variations in a predetermined parameter, said method comprising the step of establishing a first number of data points expected to represent a segmented feature of said image, establishing a threshold value of a characteristic of said data set, determining a second number of data points meeting said threshold and comparing said first and second number of data points.
