This palette contains functions for line fitting, ellipse
fitting, convexity defects and more…
Note: A vi icon with yellow background means they work on
color images. With gray background means they only work on single channel image.
With half yellow and half gray background means they work on both color and
single channel image. Others vi icon background are for either examples or high
level vis. For controls descriptions, you need to go to the vi in LabVIEW, use
help (ctrl+H) and move mouse over the controls to see them.
Finds minimum area rectangle that contains both input rectangles inside.
Calculates vertices of the input 2d box.
Calculates ellipse that fits best (in least-squares sense) to the contour.
fits line to 2D point using the simplest and the fastest least-squares
finds convex hull of 2D point set using Sklansky's algorithm.
tests whether the input contour is convex or not. The contour must be
simple, i.e. without self-intersections.
finds all convexity defects of the input contour. After this you can use
IVision_GetConvexDefectByIndex.vi to read out the convexity defects.
Get Convexity Defect by index.
Finds circumscribed circle of minimal area for given contour.
