Design outcomes

Primary

Measure	Time frame
We compare the visibility of a bleeding point between the original and the processed images using a 5-point Likert scale.	—

Secondary

Measure	Time frame
1, we calculate the average distance between a bleeding point and its surround in 3D color space and compare its color differences between the original and the processed images. 2, We compare the time until finding a bleeding point between the original and the processed images. 3, We evaluate whether the endoscopist's experience affects the subjective evaluation and the time until finding a bleeding point.	—
