As the smartphones are widely used in daily life, people are habituated to take photos in anywhere at anytime. The character photos, which contain both people and landscapes, are the most extensive ones in all kinds of photos. However, it is usually time-consuming and laborious for people to select and manage desired character photos manually. Therefore, automatic photo selection became extremely significant. Most of the existing methods select best character photos by assigning a absolute score or binary label, regardless of the photo’s content. The selected character photos are hence not satisfied. In this paper, we propose an effective automatic framework to select best character photos, which first automatically eliminates photos with unattractive character, then ranks photos and assists users to select the desired ones. Moreover, our framework is especially useful for mobile camera in practical application scenarios. To reduce the burden of photo selection and improve the efficiency of automatic selection from a large number of photos on mobile platform, we divide the photo selection into two stages: eliminating of unattractive photos based on designed efficient and effective features related to faces and human postures, and ranking the remaining photos using a two-stream convolution neural network. To ensure that informative features are selected and less useful ones are suppressed, we design and utilize the attention mechanism module in network. Experiments demonstrate the effectiveness of our method on the automatic selection of the satisfied photos from a large number of photos.
