Abstract: Salient object detection (SOD) is the operation of detecting and segmenting a salient object in a natural scene. Several studies have examined various state-of-the-art machine learning approaches for SOD. In particular, deep convolutional neural networks (CNNs) are commonly applied for SOD because of their powerful feature extraction abilities. In this paper, we investigate the semantic segmentation capability of several well-known pre-trained models, including FCNs, VGGs, ResNets, MobileNet-v2, Xception and InceptionResNet-v2. These models have been trained over an ImageNet dataset, fine-tuned on a MSRA-10K dataset and evaluated using other public datasets, such as ECSSD, MSRA-B, DUTS and THUR15k. The results illustrate the superiority of ResNet50 and ResNet18, which have mean absolute errors (MAE) of approximately 0.93 and 0.92, respectively, compared to other well-known FCN models. Moreover, the most robust model against noise is ResNet50, whereas VGG-16 is the most sensitive, relative to other state-of-the-art models.
