摘要:
A technique for optimizing object recognition is disclosed. The technique includes receiving at least one image of an object and at least one reference image. The technique further includes identifying at least one performance metric corresponding to an object recognition task. The identified performance metric is optimized to generate the corresponding optimized performance metric by determining an optimal subspace based on a determined objective function corresponding to the object recognition task and a difference between the received image and the corresponding reference image. Subsequently, the technique includes comparing the received image with the reference image based on the optimized performance metric for performing the object recognition task.
摘要:
A system and method for estimating a set of landmarks for a large image ensemble employs only a small number of manually labeled images from the ensemble and avoids labor-intensive and error-prone object detection, tracking and alignment learning task limitations associated with manual image labeling techniques. A semi-supervised least squares congealing approach is employed to minimize an objective function defined on both labeled and unlabeled images. A shape model is learned on-line to constrain the landmark configuration. A partitioning strategy allows coarse-to-fine landmark estimation.

A variable gain amplifier (VGA) with a gain thereof exponential to a control voltage thereof. The variable gain amplifier (VGA) comprises an exponential DC converter, and a linear voltage multiplier. The exponential DC converter receives the control voltage and generates an exponential voltage which is exponential to the control voltage. The linear voltage multiplier is coupled to the exponential DC converter and has a gain proportional to the exponential voltage of the exponential DC converter.

Method for relieving cough using an effective antitussive chemical compound belonging to stemoamide or tuberostemospironine and method for manufacturing pharmaceutical compositions for treating or relieving cough in human and animal subjects which including a stemoamide or tuberostemospironine compound. In addition, the antitussive property of the compounds provides a method for assessing the quality of herbs traditionally used in treating cough by analyzing the content of the effective chemical ingredient, i.e., compounds of stemoamide type and/or tuterostemospironine type. It further provides a method for identifying medicinal herbs which may be used for relieving cough by phytochemical determination of the existence of compounds that are of stemoamide or tuterostemospironine type.

Microfluidic devices, along with methods of their fabrication, are provided. The microfluidic device can include a substrate defining a microchannel formed between a pair of side walls and a bottom surface and a plurality of nanotips positioned within the microchannel and proximate to each side wall such that a boundary layer is formed along each side wall between the plurality of nanotips and the side wall upon addition of a liquid into the microchannel.

An apparatus and method, as may be used for predicting solar irradiance variation, are provided. The apparatus may include a solar irradiance predictor processor (10) configured to process a sequence of images (e.g., sky images). The irradiance predictor processor may include a cloud classifier module (18) configured to classify respective pixels of an image of a cloud to indicate a solar irradiance-passing characteristic of at least a portion of the cloud. A cloud motion predictor (22) may be configured to predict motion of the cloud over a time horizon. An event predictor (24) may be configured to predict over the time horizon occurrence of a solar obscuration event. The prediction of the solar obscuration event may be based on the predicted motion of the cloud. The event predictor may include an irradiance variation prediction for the obscuration event based on the solar irradiance-passing characteristic of the cloud.
