Image quality evaluation method based on target recognition and device thereof

The invention discloses an image quality evaluation method and device based on target recognition, and the method comprises the steps: carrying out the quality evaluation of a to-be-evaluated image according to an image recognition task performance index and a quality evaluation index of a target sub-image. According to the method and the device, the performance evaluation of the image recognition task and the quality evaluation of the detected target sub-image are integrated, the quality of the image is reversely deduced through the performance of the target recognition task, the sub-image quality evaluation can more truly reflect task requirements, and the pertinence of evaluating the image quality by combining the performance evaluation and the quality evaluation is stronger. 本发明公开了一种基于目标识别的图像质量评价方法及装置，该方法包括根据图像识别任务性能指标和目标子图像的质量评价指标，对待评价图像进行质量评价。该方法及装置综合了图像识别任务的性能评估以及检出目标子图像的质量评估，通过目标识别任务性能反推图像的质量，对子图像质量评估更能真实反映任务需求，二者结合评估图像质量的针对性更强。
