The following methods can be used to verify that the experimental environment is successfully set up:

After the preceding two steps are successfully run, if the en samling dokument eller en elektronisk lagring av data is generated under the mmsegmentation folder, the environment is successfully as shown in the following.

1. Dataset

The dataset used in the experiment can be obtained in the following methods:

• For polyp segmentation task: Polypseg: including Kvasir, - CVC-ClinicDB, CVC-ColonDB, EndoScene and ETIS dataset.
• For abdominal multi-organ segmentation task: Synapse.
• For skin lesion segmentation task: ISIC
• For nuclei segmentation task: DSB

2. Experiments We recommend that you place the project folder in a location such as a solid state drive, and put the checkpoint files generated from the experiment on a mechanical hard drive to save space, so you can choose to create a soft connection. Specific practices are as follows:

Gallbladder polyp

Medical condition

Gallbladder polyp
A polyp in the gall bladder as seen on ultrasound

Gallbladder polyps are growths or lesions resembling growths (polypoid lesions) in the wall of the gallbladder. True polyps are abnormal accumulations of mucous membrane tissue that would normally be shed by the body.

Signs and symptoms

[edit]

Most polyps do not cause noticeable symptoms. Gallbladder polyps are usually found incidentally when examining the abdomen by ultrasound for other conditions, usually abdominal pain.^{[citation needed]}

Pathology

[edit]

Most small polyps (less than 1&#;cm) are not cancerous and may remain unchanged for years.^[1] However, when small polyps occur with other conditions, such as primary sclerosing cholangitis, they are less likely to be benign.^[2] Larger polyps are more likely to develop into adenocarcinomas.^{[citation needed]}

Cholesterolosis is characterized by an outgrowth of the mucosal lining of the gallbladder into fingerlike projections due to the excessive accumulation of cholesterol and triglycerides within macrophages in the epithelial lining.^[3] These ch

Abstract

We present a new boundary sensitive framework for polyp segmentation, called Polyper. Our method is motivated by a clinical approach that seasoned medical practitioners often leverage the inherent features of interior polyp regions to tackle blurred boundaries. Inspired by this, we propose explicitly leveraging polyp regions to bolster the model’s boundary discrimination capability while minimizing computation. Our approach first extracts boundary and polyp regions from the initial segmentation map through morphological operators. Then, we design the boundary sensitive attention that concentrates on augmenting the features near the boundary regions using the interior polyp regions’s characteristics to generate good segmentation results. Our proposed method can be seamlessly integrated with classical encoder networks, like ResNet, MiT-B1, and Swin Transformer. To evaluate the effectiveness of Polyper, we conduct experiments on five pu
