The present invention provides compositions and methods for light-activated cation channel proteins and their uses within cell membranes and subcellular regions. The invention provides for proteins, nucleic acids, vectors and methods for genetically targeted expression of light-activated cation channels to specific cells or defined cell populations. In particular the invention provides millisecond-timescale temporal control of cation channels using moderate light intensities in cells, cell lines, transgenic animals, and humans. The invention provides for optically generating electrical spikes in nerve cells and other excitable cells useful for driving neuronal networks, drug screening, and therapy.

The embodiment of the invention discloses an animation image driving method based on artificial intelligence. The method comprises the following steps: collecting media data of facial expression changes when a speaker speaks voice, determining a first expression base of a first animation image corresponding to the speaker, and reflecting different expressions of the first animation image through the first expression base. After target text information used for driving the second animation image is determined, acoustic features and target expression parameters corresponding to the target text information are determined according to the target text information, the collected media data and the first expression base. Acoustic features and target expression parameters are used. A second animation image with a second expression base can be driven. According to the method and the device, the second animation image can give out the sound of the target text information spoken by the speaker through acoustic feature simulation, and the facial expression conforming to the due expression of the speaker is made in the sounding process, so that vivid substitution feeling and immersion feeling are brought to the user. The interaction experience of the user and the animation image is improved.

Compositions and methods for reducing the level of nornicotine and N′-nitrosonornicotine (NNN) in Nicotiana plants and plant parts thereof are provided. The compositions comprise isolated polynucleotides and polypeptides for cytochrome P450s that are involved in the metabolic conversion of nicotine to nornicotine in these plants. Expression cassettes, vectors, plants, and plant parts thereof comprising inhibitory sequences that target expression or function of the disclosed cytochrome P450 polypeptides are also provided. Methods for the use of these novel sequences to inhibit expression or function of cytochrome P450 polypeptides involved in this metabolic conversion are also provided. The methods find use in the production of tobacco products that have reduced levels of nornicotine and its carcinogenic metabolite, NNN, and thus reduced carcinogenic potential for individuals consuming these tobacco products or exposed to secondary smoke derived from these products.

Computer-implemented methods and computer program products for automatically transferring expressions between rigs with consistent joint structure, and for automatically transferring skin weights between different skin meshes based on joint positioning. A method is provided for transferring an expression between a plurality of source rigs and a target rig, where each rig characterizes an animated character, and each rig, in turn, is characterized by a set of joints and a skin mesh having a plurality of vertices, with each vertex characterized by a matrix of weights relating a response of the vertex to movement of associated joints. A set of offsets is calculated of joint positions of a goal expression of each source rig relative to a neutral expression of the source rig. A scaling transformation is then applied to the set of offsets to produce a scaled set of offsets, which are added, in turn, to a neutral expression of the target rig. Methods are also provided for transferring a set of skin weights between the source rigs and the target rig.

The invention relates to an image processing method and apparatus, a computer device and a storage medium. The method comprises the following steps: acquiring a first target face image in a referenceexpression state; acquiring user face key point offset information;, the user face key point offset information representing an offset amount of a facial key point of a user's face when the target expression state is compared to the reference expression state; adjusting a facial key point of the first target facial image in a reference expression state according to the user facial key point offsetinformation; in an image to be processed including a second target face image, attaching an expression texture image of the adjusted first target face image to the second target face image, wherein the second target face image and the first target face image belong to the same target. The scheme of the present application improves the accuracy of image processing.
