Methods and apparatus to detect bleeding vessels

A non-transitory computer readable medium storing instructions that, when executed by one or more processors of a computer system, cause the one or more processors to perform operations comprising:

• obtaining from an endoscopic device a spectrum image of bleeding in an upper gastrointestinal (GI) area of a patient;
• applying a filter to the spectrum image to generate a pre-enhanced image, wherein the filter enhances the spectrum image at one or more light wavelengths in the light spectrum;
• analyzing the pre-enhanced image to identify an area of interest, wherein the area of interest represents a portion of the upper GI area with an active bleed;
• applying a contrast enhancement technique to the area of interest in the pre-enhanced image to generate an enhanced contrast image;
• applying spatial filters to the enhanced contrast image to produce a final colorized image with defined blood vessels in the upper GI area of the patient.

A computer device for enhancing medical images, the computer device comprising:

• an interface unit;
• a memory storing instructions;
• and
• one or more processors configured to perform operations including:
• obtaining from an endoscopic device a spectrum image of bleeding in an upper gastrointestinal (GI) area of a patient;
• applying a filter to the spectrum image to generate a pre-enhanced image, wherein the filter enhances the spectrum image at one or more light wavelengths in the light spectrum;
• analyzing the pre-enhanced image to identify an area of interest, wherein the area of interest represents a portion of the upper GI area with an active bleed;
• applying a contrast enhancement technique to the area of interest in the pre-enhanced image to generate an enhanced contrast image;
