摘要:
In a method for detecting facial expressions of a portrait photo by an image capturing electronic device, a face captured in the portrait photo is detected. The position and range of the opened and closed facial features are detected, and the facial features within an identified range are magnified according to a specific proportion. A patch of facial features and their surroundings within a specific range is cut according to the magnified identified range, so that the patch can show a change of facial expressions and a specific range of their surroundings. A facial feature classifier is trained by a specific number of opened and closed facial feature samples based on the Adaboost algorithm and used for detecting the facial features in the patch to determine whether the facial feature is situated at an opened state or a closed state.

The present invention discloses a face tracking method for electronic camera devices. The method is applied to an electronic camera device having a face database and a face classifier, and the face database is provided for storing data such as a position, a size and a skin color prototype of a face in a previously stored preview image, and the method includes the steps of: obtaining a current preview image; determining whether or not a known face exists in the face database; defining a searching space on the current preview image; and using the face classifier to detect the searching space in the current preview image, and determining whether or not a face exists in the searching space.
摘要:
A known face guided imaging method applied for an electronic imaging device uses the scale of a known face sensed in a previous frame to define a scale range of a searching window, which adds a scale constraint into the searching window so as to search a current frame horizontally and vertically in the searching window to perform a face searching loop for a face. The invention simply sends a corresponding image patch within the scale range to a face detector for the face detection, and the searching space is constrained in a small group of scale ranges without the need of detecting the whole image of various different scales within the scale range, and thus the invention effectively reduces the huge quantity of computing values required for the detection process and greatly enhances the speed and efficiency of the face detection.

The present invention relates to a cardio myopeptidin which is isolated from the hearts of non-human healthy mammals. The molecular weight of the cardio myopeptidin is less than 10000 Dalton, the peptide content thereof being 75%˜90%, the free amino acid content 6%˜15%, the ribonucleic acid content less than 2%, and the deoxyribonucleic acid content less than 7.5%. The present invention further provides a method of producing the cardio myopeptidin and the use thereof in producing pharmaceuticals for treating cardiac disorders, specifically the use in producing pharmaceuticals for treating myocardial ischemic and reperfusion injury. The cardio myopeptidin of the present invention can work directly on myocytes, promoting the repair of injuries caused by various reasons, and providing a new way to relieve ischemic and reperfusion injury, and to promote the repair of injured myocardium.

A composition is disclosed comprising a polymer and a surfactant in a solvent exhibiting a common solubility for the polymer and the surfactant. The composition provides a dosage form for administering a drug over time.
摘要:
A sustained release dosage form is disclosed, which dosage form comprises an interior lipophilic membrane, and an exterior hydrophilic membrane comprising a peptide, that surround a composition comprising a drug. The dosage form at the end of its drug delivery period self-ruptures for enhancing its exit from the environment of use.
摘要:
Methods and compositions are described whereby poorly water-soluble beneficial agents such as vitamins and co-factors are formulated into self-emulsifying formulas (SEF) and optionally sorbing the SEF into pores of porous solid particulates, or preparing supersaturated solutions (SSS) and sorbing the SSS into pores of porous solid particulates. These formulations are useful as dosage forms with oral availability.

Locating an eye includes generating an intensity response map by applying a 3-rectangle filter and applying K-mean clustering to the map to determine the eye. Locating an eye corner includes applying logarithm transform and grayscale stretching to generate a grayscale eye patch, generating a binary map of the patch by using a threshold based on a histogram of the patch, and estimating the eye corner by averaging coordinates weighted by minimal eigenvalues of spatial gradient matrices in a search region based on the binary map. Locating a mouth corner includes generating another intensity response map and generating another binary map using another threshold based on another histogram of the intensity response map. Locating a chin or a cheek includes applying angle constrained gradient analysis to reject locations that cannot be the chin or cheek. Locating a cheek further includes removing falsely detected cheeks by parabola fitting curves through the cheeks.

A method for detecting a facial expression and repairing a smile face of a portrait photo includes the steps of: detecting a location and a range of a mouth region in an inputted portrait photo; capturing a patch in the mouth region and a predetermined peripheral range thereof; executing a comparison process to a smile state or a stiff state of the mouth region in the patch by a mouth state classifier; executing a calculation process to a repaired region of the mouth region when the mouth region is determined to be in the stiff state, in order to calculate a location of a plurality of feature points in the repaired region of the mouth region; and executing an image warping process to the location of the feature points and adjacent pixels thereof, for generating a portrait photo showing a smile state.
摘要:
An appliance assembly that can provide multiple independently positionable appliances, such as fans. The appliance assembly includes a base support, a frame coupled to the base support, and a number of appliances each contained within an appliance housing. Each appliance housing is rotatably mounted to an outer gimbal such that it is rotatable about a first axis, and each outer gimbal is mounted to the frame such that it is rotatable about a second axis. The appliance assembly can provide two degrees of freedom for positioning each of the number of appliances. The frame, outer gimbals, and appliance housing can be formed in a variety of shapes. The appliance assembly can be used, for example, with any product where it is desirable to have multiple independently positionable assemblies, such as fans, speakers, microphones, lights, and heaters.
