Anterior segment analysis apparatus, anterior segment analysis method, and non-transitory computer-readable storage medium

An anterior segment analysis method comprising:

• obtaining a tomographic image of an anterior segment including a cornea of a subject eye formed by OCT measurement;
• detecting a plurality of edges included in the tomographic image;
• performing a first joining comprising joining between edges for each of the plurality of edges based on a first joining condition;
• selecting a first edge and a second edge from among the edges joined by the first joining based on a length;
• performing a second joining comprising joining between edges with reference to each of the first edge and the second edge based on a second joining condition;
• and
• determining a boundary of a layer of the cornea of the tomographic image using the edges joined by the second joining.

A non-transitory computer-readable storage medium storing a computer program readable by a computer, the computer program, when executed by the computer, causing the computer to perform operations comprising:

• obtaining a tomographic image of an anterior segment including a cornea of a subject eye formed by OCT measurement;
• detecting a plurality of edges included in the tomographic image;
• performing a first joining comprising joining between edges for each of the plurality of edges based on a first joining condition;
• selecting a first edge and a second edge from among the edges joined by the first joining based on a length;
• performing a second joining comprising joining between edges with reference to each of the first edge and the second edge based on a second joining condition;
• and
• determining a boundary of a layer of the cornea of the anterior segment using the edges joined by the second joining.
