Canny edge detector is the most popular tool for edge detection and has many applications in the areas of image processing, multimedia and computer vision. The Canny algorithm optimizes the edge detection through noise filtering using an optimal function approximated by the first derivative of a Gaussian. It identifies the edge points by computing the gradients of light intensity function based on...
Spatial priors play crucial roles in many high-level vision tasks, e.g. scene understanding. Usually, learning spatial priors relies on training a structured output model. In this paper, two special cases of discriminative structured output model, i.e. conditional random fields (CRFs) and max-margin Markov networks (M3N), are demonstrated to perform image scene understanding. The two models are empirically...
This paper presents a new rule induction algorithm based on the extension matrix theory, and uses it to learn prosodic phrasing rules automatically for Chinese text-to-speech. Firstly, the basic idea of our algorithm is introduced. Secondly, we collected 937 sentences from news programs and built a corpus for modeling Chinese prosody, a group of feature variables are also proposed. Lastly, the data...
