Applications of Texture Perception in the Analysis of Complex Optical Imagery

Abstract

These studies examine the feasibility of using texture perceptions in scientific or technical analyses of complex optical imagery. Section 1 illustrates that reliable quantitative data can be derived from texture perceptions, provided appropriate psychometric techniques are employed. Section 2 illustrates, in the context of medical imagery screening, a procedure which may often be required to translate the idiosyncratic visual assessments of expert observers into standardized psychometric procedures, some of which might then be carried out by untrained observers. Section 3 reports studies of reliability and validity when observers follow psychometric procedures in measuring the over-all appearance of Pap smears. The report suggests that applications of texture perception could be made in a wide range of situations requiring scientific or technical analyses of complex imagery, particularly where automated assessment is not available or prohibitively expensive. A thesaurus of descriptors of complex optical imagery with 1707 entries is attached.
