	abstract =	{In color histogram based image retrieval, a user query
	specification forms a histogram to be matched with those of the images
	in the database. The accuracy of this specification determines the
	matching latitude and affects directly the effectiveness of the
	retrieval process. The retrieval process suggests some relevant human
	factors, such as people's ability to estimate percentages and
	individual characteristics such as training, experience, and
	background. A two-part laboratory study was made to understand people's
	ability to estimate percentages of single-block and multiple-block
	color. The results can be applied to enhance image retrieval systems.
	For example, the results provide different ranges of estimates, based
	on statistical percentiles. Retrieval systems can use these to
	determine appropriate values for retrieval control parameters. The
	statistics can be used to help determine likely recall and precision
	performance. Overall, the study provides deeper understanding of
	people's estimate of color percentages in images.},
