- %kvclose 'Close Boundaries of an Edge Image (K1)'
- % This MatLab function was automatically generated by a converter (KhorosToMatLab) from the Khoros vclose.pane file
- %
- % Parameters:
- % InputFile: i1 'Input Boundary Image', required: 'Input Boundary Image (result from vdrf, vgef, vsdef ...)'
- % InputFile: i2 'Input Gradient Image', required: 'Input Gradient Image (result from vdrf, vsdef, sobel...)'
- % Integer: grad 'Gradient Threshold ', default: 0: 'Gradient Threshold (used by the closing process)'
- % Integer: len 'Minimum Gap Size ', default: 1: 'Minimum Gap Size In Pixels'
- % OutputFile: o 'Output Image ', required: 'resulting output image or file'
- %
- % Example: o = kvclose({i1, i2}, {'i1','';'i2','';'grad',0;'len',1;'o',''})
- %
- % Khoros helpfile follows below:
- %
- % PROGRAM
- % vclose - Close Boundaries of an Edge Image (K1)
- %
- % DESCRIPTION
- % .I vclose
- % uses a boundary image and a gradient image as input. Then it tries to close
- % the boundaries by following the maximum gradient between two end points of
- % two contours.
- %
- % The new closing part is kept if its length is at least
- % "Minimum_Gap_Size" pixels. This parameter is used to prevent the result
- % from being covered by small contours (edges of noisy areas...).
- %
- % The minimum gradient value "Gradient_Threshold" has to be set up to
- % indicate to the closing process up to what value it can follow a maximum
- % gradient curve to close a boundary.
- %
- % This Algorithm has been written by:
- %
- %
- % Professor SERGE CASTAN, Prof CHEN and Dr ZHAO

- % EXAMPLES
- % vclose -i1 moon_edge.xv -i2 moon_grad.xv -v 5 -f 0.5 -o closed_boundary.xv
- %
- % Will use moon_edge.xv and moon_grad.xv as the edges and respectively
- % the gradient representation of an image. Then it will close the unclosed
- % boundaries using a minimum gap size of 5 pixels and a gradient threshold of 0.5
- %
- % "SEE ALSO"
- %
- % RESTRICTIONS
- % .I vclose
- % will only work with single band images. Then the first image has to be of data
- % storage type VFF_TYP_1_BYTE. The second input can be anything from VFF_TYP_1_BYTE
- % to VFF_TYP_FLOAT.
