Embodiment approach

[0124] Method 1, such as Figure 5 As shown, in step S104, according to the fusion node feature of any prediction cell, the second position of any prediction cell is obtained, which may include:

[0125] S501. Based on the fusion node feature of any prediction unit, obtain the prediction probability of any prediction unit at each candidate second position.

[0126] Taking the second position as the starting line of the predicted cell as an example, if the number of rows in the table is T, and the candidate second position includes rows 1, 2 to T, then based on the fusion node characteristics of any predicted cell, we can get The predicted probability of any predicted cell under rows 1, 2 to T.

[0127] S502. Obtain the maximum prediction probability from the prediction probability of any prediction unit at each candidate second position, and determine the candidate second position corresponding to the maximum prediction probability as the second position of any prediction uni...

Abstract

The invention provides a cell position detection method and device, and electronic equipment. The method comprises the steps: obtaining a first position of a prediction cell in a table image, wherein the first position is used for representing the position of a region occupied by the prediction cell in the table image; according to the first position, obtaining an adjacent matrix of the table image, wherein each prediction cell in the table image is a node, and the adjacent matrix is used for representing the position relation between the prediction cells; according to the first position of any prediction cell and the adjacent matrix, obtaining a fusion node feature of any prediction cell; and according to the fusion node features of any prediction cell, obtaining a second position of any prediction cell, wherein the second position is used for representing the row and / or column to which the prediction cell belongs. Therefore, the second position of the predicted cell can be obtained according to the fused node features, and the first position and the second position of the cell can be obtained at the same time.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular to a method, device, electronic device and storage medium for detecting the position of a cell. Background technique [0002] At present, tabular data has the advantages of simplicity, intuition, and ease of processing, and is widely used in people's office life. With the development of artificial intelligence technology, the requirements for automatic recognition of table data are getting higher and higher. For example, the position of cells is automatically detected from the table image, so that information extraction can be performed based on the position of the cells. However, in the cell position detection method in the related art, the detected cell position information is incomplete and has poor robustness. Contents of the invention [0003] The present application aims at at least to a certain extent solving one of the technical problems of inc...
