Abstract: A tracker is described which comprises a processor configured to receive captured sensor data depicting an object. The processor is configured to access a rigged polygon mesh model of the object and to compute a plurality of approximate surface normals of a limit surface of the rigged polygon mesh. The processor is configured to compute values of pose parameters of the model by calculating an optimization to fit the model to the captured sensor data where the optimization uses an evaluation function based on the plurality of approximate surface normals.

Abstract: Methods and devices for obtaining search results. For example, a method may include receiving, by a computing device, search information input by a current user and a target user that is associated with the search information and designated by the current user. The computing device may transmit to a server terminal a search request including the search information and the target user such that the server terminal may obtain feature information of the target user based on the search information of the search request, obtain a search result corresponding to the feature information based on the search information, and return the search result to the client terminal, which may receive and display the search result. The implementations provide an approach for obtaining search results associated with a desired target user.

Abstract: Methods disclosed herein may be methods for maintaining environmental conditions in a cabinet. Such methods may comprise determining a relative humidity set point. Such methods may comprise activating a fan configured to circulate air within said cabinet. Such methods may comprise supplying humidity by activating a heater in a fluid pan or a mist generator. Such methods may comprise measuring a relative humidity, an air temperature, and a rate of airflow in said cabinet. Such methods may comprise adjusting a duty cycle of said heater and said fan in response to said air temperature, said relative humidity, and said rate of airflow to maintain said relative humidity within a predetermined range based on the relative humidity set point. Computer-readable instructions to perform such methods may be stored on non-transitory, computer-readable media. Further, a system comprising a processor and a memory storing such computer-readable instructions may implement such methods.

Abstract: Group creation information sent by multiple instant messaging client terminals are received, wherein the group creation information includes instruction information for creating a user group and an instant messaging identification of a user logging into a respective instant messaging client terminal. Group creation information set including the same instruction information is determined. The user group is created according to the instant messaging identification included in the group creation information set.

Abstract: First ranking scores of different search objects in a search result are obtained based on a first ranking model. The first ranking scores are divided into multiple intervals. The search objects are classified into different sets of search objects corresponding to the multiple intervals. One or more search objects with one or more preset labels within a set of data objects corresponding to each interval are determined. Second ranking scores of the search objects with the preset labels are obtained based on a second ranking model. The second ranking scores are used to adjust rankings of the search objects with the preset labels within the sets of search objects of the corresponding intervals. Based on the condition of ensuring correlation of the search result, the present techniques improve consistency and continuity of the displayed search result, provide uniform user experience, and simplify algorithms to reduce data processing complexity and to improve efficiency and system processing performance.
