Abstract: Generally this disclosure describes a video communication system that replaces actual live images of the participating users with animated avatars. A method may include selecting an avatar; initiating communication; detecting a user input; identifying the user input; identifying an animation command based on the user input; generating avatar parameters; and transmitting at least one of the animation command and the avatar parameters.

Abstract: The present invention discloses a highly effective in situ treatment method for endogenous pollution in sludge, belonging to the field of environmental engineering water treatment. In view of the problem that it is difficult to effectively treat the endogenous pollution of river sludge, the present invention provides the highly effective in situ treatment method for endogenous pollution in sludge, which specifically adopts a combination of phoslock, calcium peroxide and aluminum modified zeolite to perform in-situ remediation of sludge, effectively inhibit the release of endogenous pollution of sludge, facilitate the ecological treatment of polluted water subsequently, and finally realize the long-term water improvement against pollution.

Abstract: Methods and apparatus to match images using semantic features are disclosed. An example apparatus includes a semantic labeler to determine a semantic label for each of a first set of points of a first image and each of a second set of points of a second image; a binary robust independent element features (BRIEF) determiner to determine semantic BRIEF descriptors for a first subset of the first set of points and a second subset of the second set of points based on the semantic labels; and a point matcher to match first points of the first subset of points to second points of the second subset of points based on the semantic BRIEF descriptors.

Abstract: The present disclosure relates to the field of engineering vehicles, and, a cab frame, a cab and an engineering vehicle. A cab frame provided by the present disclosure includes a support framework, where the support framework includes a bottom frame, a top frame, and a four-upright-column structure supported between the bottom frame and the top frame; the four-upright-column structure includes two front upright columns and two rear upright columns, and an inner dimension of the cab frame increases along the bottom-to-top direction. As the cab frame is configured into a four-upright support structure with a large upper portion and a small lower portion, the cab is provided with a smaller dimension of the lower portion, a larger dimension of the upper portion, and fewer uprights at the same time, which reduces visual field obstruction arising from a baseplate and uprights and provides sufficient movement space for an operator head.

Abstract: Disclosed is a rotating cored-type biological treatment device for wastewater with low carbon content and use thereof. The device includes a composite frame (1), several biological packing columns (2), a rotating tray (3), a rotating shaft, and a base (4), wherein the biological packing columns (2) are detachably mounted inside the composite frame (1); the rotating shaft is vertically arranged on the base (4) and can rotate; the rotating tray (3) is fixedly sheathed on the rotating shaft, and the composite frame (1) is disposed on the rotating tray (3); and the rotating tray rotates with the rotating shaft, which driving the composite frame (1) and the biological packing columns (2) therein to rotate. The rotating cored-type biological treatment device has the advantages of high efficiency and being renewable and environment-friendly, etc.

Abstract: Techniques are provided for estimation of human orientation and facial pose, in images that include depth information. A methodology embodying the techniques includes detecting a human in an image generated by a depth camera and estimating an orientation category associated with the detected human. The estimation is based on application of a random forest classifier, with leaf node template matching, to the image. The orientation category defines a range of angular offsets relative to an angle corresponding to the human facing the depth camera. The method also includes performing a three dimensional (3D) facial pose estimation of the detected human, based on detected facial landmarks, in response to a determination that the estimated orientation category includes the angle corresponding to the human facing the depth camera.

Abstract: A long-term object tracker employs a continuous learning framework to overcome drift in the tracking position of a tracked object. The continuous learning framework consists of a continuous learning module that accumulates samples of the tracked object to improve the accuracy of object tracking over extended periods of time. The continuous learning module can include a sample pre-processor to refine a location of a candidate object found during object tracking, and a cropper to crop a portion of a frame containing a tracked object as a sample and to insert the sample into a continuous learning database to support future tracking.

Abstract: A system, article, and method of neural network object recognition for image processing includes customizing a training database and adapting an instance segmentation neural network used to perform the customization.

Abstract: An example apparatus for generating synthesized images includes a receiver to receive a frame, a mask and external images. The apparatus also includes a foreground augmenter to generate augmented foregrounds in the frame based on the mask. The apparatus includes a background augmenter to generate augmented backgrounds based on the frame, the mask, and the external images. The apparatus also further includes an image synthesizer to generate a synthesized image based on the generated augmented foregrounds and the augmented backgrounds.
