Feature-Centric Lesion Detection and Retrieval in Thoracic Images

Advances in medical digital imaging have greatly benefited patient care. Computer-aided diagnosis is increasingly being used to facilitate semior fullyautomatic medical image analysis and image retrieval. While different tasks involve different methodologies in this domain, these tasks normally require image feature extraction as an essential component in the algorithmic framework. In this Chapter, we focus on image feature modeling in lesion detection and image retrieval for thoracic images. For both tasks, we first review the state-of-the-art and then present some of our own work in more detail.
