Embodiment 1
[0050] like figure 1 The shown screening method for pictures used for esophageal cancer model training comprises the following steps:
[0051] Enter the static picture to be filtered;
[0052] According to the feature of described static picture, adopt clustering algorithm to carry out clustering to static picture, obtain several classes of static pictures;
[0053] The distance function was used to screen the static pictures in each cluster, and the static pictures with low similarity were obtained as training samples for establishing an esophageal cancer recognition model.
[0054] The step of using the distance function to filter the static pictures in each cluster includes:
[0055] A distance function is used to calculate the distance values between all still pictures in the same cluster, and the distance function is:
[0056]
[0057] Among them, P i and P j are respectively the i-th static picture and the j-th static picture in the same cluster, P i (m,n) is ...
Embodiment 2
[0067] A screening system for images used in esophageal cancer model training, including:
[0068] The input module is used for inputting static pictures to be screened;
[0069] The screening module is used to apply a clustering algorithm to cluster the static pictures to obtain several categories of static pictures, and use a distance function to screen the static pictures in each cluster to obtain static pictures with a low degree of similarity as used for establishing an esophageal cancer identification model training samples;
[0070] The output module outputs the training samples obtained by screening;
[0071] The steps of the screening module using a distance function to screen the static pictures in each cluster include:
[0072] A distance function is used to calculate the distance values between all still pictures in the same cluster, and the distance function is:
[0073]
[0074] Among them, P i and P j are respectively the i-th static picture and the j-...
Embodiment 3
[0080] A storage medium, including a stored computer program, wherein, when the computer program is running, the device where the storage medium is located is controlled to execute the screening method described in any of the foregoing embodiments.
[0081] In this embodiment, the above-mentioned storage medium is a computer-readable storage medium. If the colonoscopy quality assessment device is implemented in the form of a software function unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. medium. Based on this understanding, the present invention realizes all or part of the processes in the methods of the above embodiments, and can also be completed by instructing related hardware through computer programs. The computer program can be stored in a computer-readable storage medium, and the computer When the program is executed by the processor, the steps in the above-mentioned various method embodiments can be realized. ...
