We present a novel approach to localizing parts in images of human faces. The approach combines the output of local detectors with a nonparametric set of global models for the part locations based on over 1,000 hand-labeled exemplar images. By assuming that the global models generate the part locations as hidden variables, we derive a Bayesian objective(More)
We present two novel methods for face verification. Our first method - “attribute” classifiers - uses binary classifiers trained to recognize the presence or absence of describable aspects of visual appearance (e.g., gender, race, and age). Our second method - “simile” classifiers - removes the manual labeling required for(More)
We introduce the use of describable visual attributes for face verification and image search. Describable visual attributes are labels that can be given to an image to describe its appearance. This paper focuses on images of faces and the attributes used to describe them, although the concepts also apply to other domains. Examples of face attributes include(More)
We have created the first image search engine based entirely on faces. Using simple text queries such as " smiling men with blond hair and mustaches, " users can search through over 3.1 million faces which have been automatically labeled on the basis of several facial attributes. Faces in our database have been extracted and aligned from images down-loaded(More)
We describe the first mobile app for identifying plant species using automatic visual recognition. The system – called Leafsnap – identifies tree species from photographs of their leaves. Key to this system are computer vision components for discarding non-leaf images, segmenting the leaf from an untextured background, extracting features representing the(More)
With the fast development of wireless communication technologies and semiconductor technologies, the wireless sensor network (WSN) has been widely used in many applications. As an application of the WSN, the wireless medical sensor network (WMSN) could improve health-care quality and has become important in the modern medical system. In the WMSN,(More)
In this paper, we present a complete system for automatic face replacement in images. Our system uses a large library of face images created automatically by downloading images from the internet, extracting faces using face detection software, and aligning each extracted face to a common coordinate system. This library is constructed off-line, once, and can(More)
Eighteen male lambs (8–9 months of age, 25.00 ± 0.90 kg body weight) were divided into three groups of six animals in each and fed a total mixed ration (TMR) containing concentrate mixture (30% maize grain, 27% soybean meal, 40% wheat bran, 2% mineral mixture, and 1% common salt) and wheat straw in 65:35 ratio and supplemented with selenium (Se) as sodium(More)
Superficial siderosis of the central nervous system results from hemosiderin deposition in the subpial layers of the brain and spinal cord. A clinical history of subarachnoid hemorrhage is often absent. Patients present with slowly progressive gait ataxia and sensorineural hearing impairment. A history of prior intradural surgery or trauma is common. With(More)
The authenticated key agreement protocol is an important security protocol for the session initiation protocol, which allows the and the server to authenticate each other and generate a shared session key for privacy, integrity , and non-repudiation in their communications. Recently, Zhang et al. proposed a new authenticated key agreement protocol for the(More)
