1. A method for defining edge location parameters in a machine vision inspection system user interface, the method comprising: defining a plurality of edge detection parameters for a region of interest (ROI) of an edge location video tool; displaying a multi-dimensional parameter space representation of possible combinations of the plurality of edge detection parameters; displaying a parameter combination indicator located within the multidimensional parameter space representation, the parameter combination indicator being configured to indicate a combination of at least two of the plurality of edge detection parameters based on its location such that changing the location of the parameter combination indicator adjusts each of the at least two edge detection parameters at the same time, wherein a configuration of the parameter combination indicator may be modified by a user, the configuration including at least the location of the parameter combination indicator; and displaying at least one edge feature representation window that represents edge features located in the ROI of the edge location video tool, wherein the at least one edge feature representation window responds to the configuration of the parameter combination indicator as it is modified by a user such that edge features detectable by the combination of edge detection parameters indicated by a current configuration of the parameter combination indicator are automatically updated in the at least one edge feature representation window.
