Natsumushi: Image measuring software for entomological studies

Abstract

Natsumushi is a free image analysis software that offers easy handling and quick measurement, designed especially for entomologists as the main users. The software enables measurement of: (i) color features of a specific region; (ii) area size; (iii) length of simple lines or polylines; and (iv) number of points or their x-y coordinates. Users can specify the region for measurement either manually or automatically by using image thresholding operations.
