Medical image processing method, apparatus, and device, medium, and endoscope

A medical image processing apparatus, comprising:

• one or more processors;
• and one or more memories, the memory storing computer-readable code, wherein the one or more processors are configured to execute the computer-readable code to:
• determine a target mask of a target object in a medical image and a reference mask of a reference object in the medical image, the target mask indicating a position and a boundary of the target object, and the reference mask indicating a position and a boundary of the reference object, wherein the reference object is a non-tissue object with a known reference size;
• determine a feature size of the target object in the medical image based on the target mask;
• determine a feature size of the reference object in the medical image based on the reference mask;
• and
• determine a target size of the target object based on the feature size of the reference object, a mapping relationship between the feature size of the reference object and the known reference size of the reference object, and the feature size of the target object.

A non-transitory computer-readable storage medium, storing instructions, the instructions, when executed by a processor, causing the processor to perform:

• determining a target mask of a target object in a medical image and a reference mask of a reference object in the medical image, the target mask indicating a position and a boundary of the target object, and the reference mask indicating a position and a boundary of the reference object, wherein the reference object is a non-tissue object with a known reference size;
• determining a feature size of the target object in the medical image based on the target mask;
• determining a feature size of the reference object in the medical image based on the reference mask;
• determining at least one mapping parameter used in a mapping relationship between the feature size of the reference object and the known reference size of the reference object based on the known reference size and the feature size of the reference object;
• and
• determining a target size of the target object based on the feature size of the reference object, the at least one mapping parameter used in the mapping relationship between the feature size of the reference object and the known reference size of the reference object, and the feature size of the target object.
