基于美学与显著性感知回归的图像裁剪方法

Image Cropping Based on Aesthetic and Saliency PerceptionRegression

  • 摘要: 针对现有图像裁剪方法存在美学与裁剪内在关联模糊及构图完整性缺失问题, 本文提出一种可解释的美学与显著性感知的图像裁剪方法. 首先, 构建特征提取网络, 分别生成美学区域分布图与视觉显著性特征图; 其次, 通过空间感受损失融合调整两类特征, 定位关键构图要素; 最后, 设计基于锚点引导回归器, 实施从粗粒度到细粒度的裁剪框预测. 在FCDB和FLMS数据集上的实验表明, 该方法在保持主体完整性的同时, 图像裁剪的精度优于现有主流方法. 在FLMS数据集上, IoU平均提升约1.72%, mBDE平均提升约17.05%.

     

    Abstract: Aiming at the problems of unclear intrinsic connection between aesthetics and cropping and lack of compositional integrity in existing image cropping methods, this paper proposes an interpretable aesthetic and saliency-aware image cropping method. Firstly, a feature extraction network is constructed to generate the aesthetic region distribution map and the visual saliency feature map respectively; secondly, the two types of features are fused and adjusted through the spatial receptive loss to locate the key compositional elements; finally, an anchor-guided regressor is designed to implement the cropping box prediction from coarse-grained to fine-grained. Experiments on the FCDB and FLMS datasets show that while maintaining the integrity of the main subject, the accuracy of image cropping of this method is superior to that of the existing mainstream methods. On the FLMS dataset, the IoU is increased by approximately 1.72% on average, and the mBDE is improved by approximately 17.05% on average.
