		const string &	imageDirectoryPath,
		size_t	begIndex = 0,
		size_t	endIndex = 0,
		const string &	blacklistPath = ""
	)

Load image names and ground-truth labels from the image directory and the ground truth label file.

Precondition

validationLabelPath exists and is valid regular file

imageDirectoryPath exists and is valid directory

labels in validation file correspond to images which are in lexicographical order with the image name

image index starts at 1

begIndex and endIndex are end-inclusive

Parameters

[in]	validationLabelPath	Path to validation label file
[in]	imageDirectoryPath	Path to directory containing validation images
[in]	begIndex	Begin index of images to be loaded. Inclusive
[in]	endIndex	End index of images to be loaded. Inclusive
[in]	blacklistPath	Path to blacklist file

Returns

A map mapping image file names to their corresponding ground-truth labels
