摘要： A custom dental irrigation device has: a user dentition model; a custom made mouthpiece made according to the user dentition model, a pump configured to pump fluid to the mouthpiece; a suction pump configured to remove fluid from the mouthpiece; a fluid tank; and a controller. The custom made mouthpiece is configured to deliver fluid to the dental target while removing used irrigation fluid. The mouthpiece is fabricated with 3-D print techniques. The mouthpiece is designed in two pieces to cover an upper portion of a dental target and a lower portion of a dental target separately. The mouthpiece has an inner surface following the shape of the user dentition model, wherein the inner surface touches the gingiva tissue to form a sealed space once the mouthpiece is set in a user's mouth, whereby fluid is delivered to the dental target, and removed from the sealed space.

摘要： Fluorescence in situ hybridization (FISH) enables the detection of specific DNA sequences in cell chromosomes by the use of selective staining. Due to the high sensitivity, FISH allows the use of multiple colors to detect multiple targets simultaneously. The target signals are represented as colored dots, and enumeration of these signals is called dot counting. Using a two-stage segmentation framework guarantees locating all potential dots including overlapped dots.

摘要： An interactive segmentation framework for 3-D teeth CT volumetric data enables a user to segment an entire dental region or individual teeth depending upon the types of user input. Graph cuts-based interactive segmentation utilizes a user's scribbles which are collected on several 2-D representative CT slices and are expanded on those slices. Then, a 3-D distance transform is applied to the entire CT volume based on the expanded scribbles. Bony tissue enhancement is added before feeding 3-D CT raw image data into the graph cuts pipeline. The segmented teeth area is able to be directly utilized to reconstruct a 3-D virtual teeth model.

摘要： A system and method for facilitating inhibiting banding in video data, in part by anticipating when banding may occur given certain encoder parameters. An example method includes receiving an input stream of video data; extracting feature information characterizing the stream of video data; using a feed-forward neural network to process the feature information to estimate when a particular block of the stream of video data will exhibit an artifact when encoded using certain Quantization Parameters (QPs); incorporating the indication into metadata associated with the stream of video data; and transferring the stream of video data and metadata to a video encoder. In a more specific embodiment, the feature information includes color information and texture information, and the neural network includes a feed-forward neural network that includes a classifier with a sigmoid activation function, and which has been trained using a cross-entropy cost function.
