Device and method for determining objects in a color recording

摘要

A device for determining objects in a color recording has an identifier, a feature extractor and a classifier. The identifier is implemented to identify the connected regions whose size or shape correspond to a predetermined condition from a plurality of connected regions existing in a binary image derived from a color recording based on a size or a shape of these connected regions. The feature extractor is implemented, for each of the identified connected regions, to extract a feature set from the color recording. The classifier is implemented to classify the identified connected regions into at least two disjunct groups based on the extracted feature sets for the identified connected regions.

1. A device for determining objects in a color recording, comprising:
an identifier which is implemented to identify connected regions whose size or shape corresponds to a predetermined condition from a plurality of connected regions corresponding to chromatin-comprising objects and existing in a binary image derived from the color recording based on a ratio of green components with respect to blue components in the color recording, based on a shape or a size of the connected regions; a feature extractor for extracting a feature set for each of the identified connected regions from the color recording; a classifier for classifying the identified connected regions into at least two disjunct groups based on the extracted feature sets for the identified connected regions; and wherein the objects to be determined are plasmodia and the color recording is a visual field of at least a part of a thick blood film.
