IMAGE MEASUREMENT APPARATUS, IMAGE MEASUREMENT METHOD, AND IMAGE MEASURING PROGRAM STORAGE MEDIUM

摘要

A partial image extracting unit extracts images of a predetermined size and constant magnification from a tissue region. A mask generating unit generates a mask for removing a region not intended for measurement from the tissue region for each extracted image. A complete mask generating unit generates a temporary complete mask in which the masks generated for each of the images are integrated together, and generates a complete mask in which close portions among unmasked portions in the temporary complete mask are unified into one or more target regions. A measuring unit measures information pertaining to an object to be measured included in the image, and this information is measured for each of the images extracted by the partial image extracting unit. A region information calculating unit calculates, for each target region, information pertaining to the object to be measured from the measured information and from the complete mask.

主权项

1. An image measurement apparatus, comprising:
a issue region recognition unit configured to recognize a tissue region from an image which is imaged by staining tissue including a measurement object and a non-measurement object; a partial image extraction unit configured to extract images of an predetermined size and a fixed magnification from the tissue region; a mask generation unit configured to generate a mask to remove a non-measurement object region, which is a region in which the non-measurement object exists, from the tissue region for each of the extracted images; a whole mask generation unit configured to generate a provisional whole mask by merging masks generated for each of the images and generate a whole mask by merging portions which are not masked in the provisional whole mask, the portions adjacent to each other into one or more object regions; a measurement unit configured to measure, for each of the images extracted by the partial image extraction unit, information on the measurement object contained in the images; and a region information computation unit configured to compute, based on the measured information and the whole mask, information on the measurement object for each of the object regions.
