摘要:
Systems and methods of automatically editing video data containing a sequence of video frames are described. Respective frame characterizing parameter values and respective camera motion parameter values are determined for each of the video frames. A respective frame score is computed for each of the video frames based on the determined frame characterizing parameter values. Segments of consecutive ones of the video frames are identified based at least in part on a thresholding of the frame scores. Shots of consecutive ones of the video frames having motion parameter values meeting a motion quality predicate are selected from the identified segments. An output video is generated from the selected shots.

Systems and methods of producing an output video are described. In one approach, respective frame scores are assigned to video frames of input videos containing respective sequences of video frames. Shots of consecutive video frames are selected from the input videos based at least in part on the assigned frame scores. An output video is generated from the selected shots.

A method and system are disclosed for onboard camera video editing. A video clip is segmented into at least one video segment having frames and the video quality of at least one frame is assessed to derive a quality score per frame and an average quality score for the video segment. To optimize quality of the video captured and to increase free memory space, at least one video segment is removed from the digital memory based on the quality score per frame and the average quality score.

A system and method for indexing multimedia files utilizes audio characteristics of predefined audio content contained in selected multimedia segments of the multimedia files to distinguish the selected multimedia segments. In the exemplary embodiment, the predefined audio content is speech contained in video segments of video files. Furthermore, the audio characteristics are speaker characteristics. The speech-containing video segments are detected by analyzing the audio contents of the video files. The audio contents of the speech-containing video segments are then characterized to distinguish the video segments according to speakers. The indexing of speech-containing video segments based on speakers allows users to selectively access video segments that contain speech from a particular speaker without having to manually search all the speech-containing video segments.

Methods, systems, and computer readable media with executable instructions, and/or logic are provided for incremental image clustering. An example method for incremental image clustering can include identifying, via a computing device, a number of candidate nodes from among evaluated leaf image cluster (LIC) nodes on an image cluster tree (ICT) based on a similarity between a feature of a new image and an average feature of each of the evaluated LIC nodes. The evaluated nodes include at least one node along each path from a root node to either a leaf node or a node having a similarity exceeding a first threshold. A most-similar node can be determined, via the computing device, from among the number of candidate nodes. The new image can be inserted to a node associated with the determined most-similar node, via the computing device.

The disclosure relates to a system and a method for generating clothing feature data representative of at least one clothing feature of a piece of clothing being worn by the person in a set of images, and training a discriminative clothing classifier using the clothing feature data to provide a personal clothing model that corresponds to the piece of clothing. The personal clothing model can be used to identify additional images in which the person appears.
摘要:
The disclosure is related to a system and method for learning robust clothing clustering based on a cluster ensemble technique applied to the clothing features of images to improve clustering of images. Different types of clothing features that are complementary to each other are computed to provide extensive description of the clothing in the images. Multiple partitions are computed based on the clothing features to generate a cluster ensemble set. A consensus function is applied to the multiple partitions to generate a final clothing consensus clustering that encompasses the information contained in the multiple partitions. A system and method are disclosed for clustering images based on the clothing of one or more persons in the images.

A transparent solar concentrator is provided for converting solar energy into electrical energy. The solar concentrator includes a first light transmissive substrate, a plurality of solar cells for receiving solar energy and converting the solar energy into electrical energy, the plurality of solar cells positioned relative to the first substrate, and a plurality of light redirecting elements arranged in the first light transmissive substrate. Each of the plurality of light redirecting elements is configured to direct light incident on a first side of the first light transmissive substrate to a respective one of the plurality of solar cells on an opposite side of the first light transmissive substrate.

An illumination system includes a light source and a reflector. The reflector includes a first optical interface adjacent the light source which redirects light emitted from the light source and incident on the first optical interface via Fresnel reflection. In addition, the reflector includes a second optical interface adjacent the first optical interface on a side opposite the light source, which reflects light passing through the first optical interface via total internal reflection back towards the first optical interface. Also, a light collection system includes such a reflector.
