AI Technical Summary
Technical Problem
The nearshore and sea sample data in the SAR image ship target data center are imbalanced, resulting in the model's low detection accuracy of nearshore ship targets.
Method used
By augmenting the nearshore sample data, the specific steps include binarization processing, open operation, closed operation, flood filling, element-by-element addition and synthesis of images, and processing isolated areas based on XML files to eliminate noise, and achieve balance between nearshore and sea data.
Benefits of technology
It effectively increases the proportion of nearshore ship targets in the data set and improves the accuracy of model detection of nearshore ship targets.

Abstract
The invention discloses a novel SAR image ship target data balancing method, and the method comprises the steps: carrying out the expansion of the near-shore sample data through a series of processing measures when the near-shore and marine sample data in an SAR image ship target data set are unbalanced, can effectively improve the proportion of a near-shore ship target in the data set, and improves the precision of the data set. According to the method, the balance of the offshore target data and the offshore target data is realized, and the detection precision of the offshore target can be effectively improved under the condition that the detection effect of the offshore ship target is poor.
