Embodiment 1
[0045] like figure 1 Shown: A data preprocessing method based on image feature refinement, including the following steps:
[0046] S1: The step of calculating the effective area, performing mask processing on the original image to obtain the training image, and calculating the effective area of the training image. The effective area includes the positive sample area and the negative sample area. The value of the effective area is calculated through opencv mask processing. The positive sample in the positive sample area is manually marked by a professional doctor, and the negative sample in the negative sample area is the area other than the positive sample.
[0047] S2: training data collection step, constructing a sliding window, moving the position of the sliding window on the training picture, and collecting training data when the digital center of the sliding window is located at the boundary or inside of the effective area.
[0048] S3: In the deep learning step, the c...
Embodiment 2
[0063] The embodiment also discloses a data preprocessing system based on image feature refinement.
[0064] like Figure 7 Shown: a data preprocessing system based on refinement of image features, including a collection terminal and a server. The collection terminal is wirelessly connected to the server through an existing wireless communication module. In this embodiment, the wireless communication module uses VG's VG30S4T-X1 type wireless communication module. The function of the acquisition terminal can be realized through the existing medical microscope, and the server can be a Lenovo 2U rack server.
[0065] specific,
[0066] Collection terminals, including:
[0067] The image acquisition module is used to acquire medical original pictures. Existing medical microscopes are used to collect the original pictures of medicine, and the BD-SW40 biological microscope of Boshi Jingda is used in this embodiment.
[0068] server, including:
[0069] The mask calculation mod...
