摘要： A computing device is used to capture image data of a physical environment. The image data is analyzed to determine color information for colors represented in the physical environment and to determine scene information that describes a room type associated with the physical environment. A palette of colors is assembled using the colors from the color information and provided for display. Upon selection of a color from the palette of colors, a product associated with the selected color and with the room type is provided for display.

摘要： Various embodiments of a framework which allow, as an alternative to resource-taxing decompression, efficient computation of feature maps using a compressed content data subset, such as video, by exploiting the motion information, such as a motion vector, present in the compressed video. This framework allows frame-specific object recognition and action detection algorithms to be applied to compressed video and other media files by executing only on I-frames in a Group of Pictures and linearly interpolating the results. Training and machine learning increases recognition accuracy. Yielding significant computational gains, this approach accelerates frame-wise feature extraction I-frame/P-frame/P-frame videos as well as I-frame/P-frame/B-frame videos. The present techniques may also be used for segmentation to identify and label respective regions for objects in a video.

摘要： The claimed subject matter provides systems and/or methods that employ a control component integrated in a light bulb to control the light bulb wirelessly. The wireless light bulb can include a light source, a control component that manages operation of the light source, an input component that wirelessly obtains input signals that can be utilized by the control component, and a power source. For instance, the light source can be one or more light emitting diodes (LEDs) and/or the power source can be one or more batteries. Moreover, the input component can receive the input signals (e.g., radio frequency, infrared, . . . ) from a remote control, a sensor, a differing wireless light bulb, a radio frequency identifier (RFID) tag, etc. Further, the wireless light bulb can be mechanically coupled to a lighting fixture, where the lighting fixture may or may not be electrically coupled to an alternating current (AC) power source.

摘要： Various embodiments identify candidate phrases users have used to reference a product in previous searches by analyzing query logs of a search engine. Upon identifying a candidate phrase within a volume of unstructured text, the candidate phrase is compared against a corpus of contemporary language. A frequency of each candidate phrase in contemporary language and the same in the query logs are determined and used as an indication to distinguish between genuine product references in the text or their normal use in common language in order to determine whether the volume of unstructured text is suitable, based on the number of references, for a hyperlink to a product page for the product of an electronic marketplace. Furthermore, behavioral data associated with user interaction with various aspects of the hyperlinks can be tracked over time to better identify suitable product references and tailor future hyperlink suggestions.

摘要： Various embodiments provide a method for computing color descriptors of product images. For example, a number of fine color representatives can be determined to describe color variation in an image as a histogram by assigning a saturation value and a brightness value to a plurality of color hues. For each pixel of the image, the closest color among a defined fine color representative set is computed. In this example, each of the pixels is assigned a color ID corresponding to their closest matching fine color representative and at least one family color ID corresponding one or more pure color families. In this example, a histogram of the color representatives and a histogram for the color families are computed. A single color vector descriptor for the image is then determined by combining the family histogram with the color representative histogram.

摘要： Various embodiments enable a user editing a document to tag product references in the document. These product references can then be recognizable when the document is published online, thereby enabling ad units (or other personalized units associated with the content) to be inserted either at a location associated with a particular product reference or within the document in a designated location. For example, when editing or drafting a document, a client-side tool could enable a user to tag particular words within the text to create a hyperlink to product pages of an electronic marketplace. In another example, a client-side tool could auto-insert a list of words associated with subject matter of the same. Accordingly, mentions of these words in content could be auto-converted into text-links or hyperlinks to a respective items page of the electronic marketplace.
