Detailed Description

Calculate length of the curve objects in the slice.

Function Documentation

function STATS = ib_calcCurveLength	(		slice,
			pixSize,
			CC
	)

Calculate length of the curve objects in the slice.

It is possible to measure the length of both closed and non-closed curves. The images are subject to thinning, so that the curves have width of 1 pixel.

Parameters

slice	a 2D slice [1:height, 1:width], class uint8 with drawn curves.
pixSize	[optional] a structure with pixel sizes. The required fields .x and .y; can be empty
CC	[optional] a structure with detected labels, returned by regionprops function

Return values

STATS

a structure with CurveLengthInPixels or CurveLengthInUnits field that has the length of the curve segment and the PixelIdxList field with indeces of pixels in each segment.

Required fields of CC:

Required fields of pixSize:
