The OCRopus system is an open source OCR system developed for book capture and digital library applications. It is designed to be a multilingual system in which all components are easily pluggable and replaceable. In this paper, I describe recent progress, on-going work, and preliminary results in the development of the OCRopus system, including the new(More)
State-of-the-art results of semantic segmentation are established by Fully Convolutional neural Networks (FCNs). FCNs rely on cascaded convolutional and pooling layers to gradually enlarge the receptive fields of neurons, resulting in an indirect way of modeling the distant con-textual dependence. In this work, we advocate the use of spatially recurrent(More)
Gesture typing is an efficient input method for phones and tablets using continuous traces created by a pointed object (e.g., finger or stylus). Translating such continuous gestures into textual input is a challenging task as gesture inputs exhibit many features found in speech and handwriting such as high variability, co-articulation and elision. In this(More)
This thesis addresses the problem of visual recognition under two sources of variability: geometric and photometric. The geometric deals with the relation between 3D objects and their views under parallel, perspective, and central projection. The photometric deals with the relation between 3D matte objects and their images under changing illumination(More)
