Detailed Description

This class contains static properties and methods specific to the eVision.EasyColor library.

Remarks:

License(s): EasyColor

Member Function Documentation

◆ AlphaBlend()

None eVision.EasyColor.AlphaBlend	(	eVision.EROIC24	source,
		eVision.EROIC24	destination,
		float	opacity )

static

Draws an image over an other.

Parameters

source	Foreground image.
destination	Background image.
opacity	Opacity of the foreground image.

◆ AssignNearestClass()

None eVision.EasyColor.AssignNearestClass	(	eVision.EROIC24 \| None	sourceImage,
		eVision.EROIBW8 \| None	destinationImage,
		eVision.EC24Vector \| None	classCenters )

static

Assigns to every pixel of the source image the nearest class index plus one and stores its value in the destination image.

Remarks:

This generates a labeled gray-level image for use with EasyObject (see eVision.EImageEncoder and eVision.Segmenters.ELabeledImageSegmenter).

Note: The class index plus one is stored instead of the class index because EasyObject will never code class 0 objects.

Color image segmentation allows you to decompose a color image in different regions by assigning a "class" (integer index) to every pixel. The nearest neighbor method is used, i.e. for each class a representative center is specified, and a given pixel is associated to the class with the closest center.

Color image segmentation can be used in conjunction with EasyObject to perform blob analysis on the segmented regions.

To use the color segmentation functions, the set of class centers must be specified as a vector of eVision.EC24 elements. In this sense, the method is termed supervised clustering. A good way to obtain these values is to compute the average color in an ROI.

Unsupervised clustering is also made available by implementing the so called K-means method that automatically improves an initial choice of class centers.

Parameters

sourceImage	Pointer to the source image/ROI.
destinationImage	Pointer to the destination gray-level image/ROI.
classCenters	Pointer to the vector of the class centers.

◆ AssignNearestClassCenter()

None eVision.EasyColor.AssignNearestClassCenter	(	eVision.EROIC24 \| None	sourceImage,
		eVision.EROIC24 \| None	destinationImage,
		eVision.EC24Vector \| None	classCenters )

static

Assigns to every pixel of the source image the nearest class center and stores its value in the destination image.

◆ ClassAverages()

None eVision.EasyColor.ClassAverages	(	eVision.EROIC24 \| None	sourceImage,
		eVision.EC24Vector \| None	classCenters,
		eVision.EColorVector \| None	averages )

static

Computes the average source pixel colors for every class separately.

Remarks:

This allows measuring the actual average color of the segmented regions.

Color image segmentation allows you to decompose a color image in different regions by assigning a "class" (integer index) to every pixel. The nearest neighbor method is used, i.e. for each class a representative center is specified, and a given pixel is associated to the class with the closest center.

Color image segmentation can be used in conjunction with EasyObject to perform blob analysis on the segmented regions.

To the color segmentation functions, the set of class centers must be specified as a vector of eVision.EC24 elements. In this sense, the method is termed supervised clustering. A good way to obtain these values is to compute the average color in an ROI.

Unsupervised clustering is also made available by implementing the so called K-means method that automatically improves an initial choice of class centers.

Parameters

sourceImage	Pointer to the source image/ROI.
classCenters	Pointer to the vector of the class centers.
averages	Pointer to the vector of the average color values.

Color image segmentation can be used in conjunction with EasyObject to perform blob analysis on the segmented regions.

Parameters

sourceImage	Pointer to the source image/ROI.
