ABSTRACT

In this paper, we studied how to apply slicing techniques to 4K and 8K images using high-resolution drone data, and used them to detect and de-identify personal information objects (car, people), and designed and implemented a system that detects and visualizes illegal crop objects in de-identified images. For privacy object detection and de-identification, single-stage techniques such as Yolov5 and Gaussian Blurring were applied, SwinTransformer, Soft-Teacher, and Fast-RCNN techniques were applied to detect illegal crop objects, and SAHI open source framework was used as image slicing techniques. The illegal crop object detection model used an ensemble Soft-Teacher model using SwinTransformer as a Backbone network and Fast-RCNN as a detector. Experiments by applying image slicing techniques to this model showed that the mAP was 0.663, which is improved from 0.456, which is the mAP of the model without applying the conventional image slicing techniques.
