Title: Manufacturing method for thermoelectric element and the thermoelectric element prepared therefrom
Inventor: KIM HYUCK JUNG
IPC: H01L35/18
Filed: 2018-08-22
Abstract: The present invention relates to a method for manufacturing a thermoelectric generation element with reduced volume and increased density by manufacturing a thermoelectric generation element before sintering by injecting a thermoelectric generation material to a molding frame having desired standards and shape and applying pressure to the same and sintering the thermoelectric generation element before sintering together with the molding frame, wherein a phenomenon that both p and n type thermoelectric generation elements shrink and have increased density at a sintering temperature of 530°C is used.

Title: A method for filtering spurious pixels in a depth-map
Inventor: VANDAME BENOIT
IPC: G06T7/50
Filed: 2018-09-28
Abstract: The present invention relates to a method for filtering spurious pixels in a depth map. According to the present invention, the filtering of a depth map is important to remove spurious pixels. A problem of filtering the spurious pixels is to remove the same while maintaining boundaries of real details of the depth map. A known approach for filtering the spurious pixels is to use a bilateral filter. The bilateral filter provides efficient filtering, capable of maintaining sharp edges of the depth map while smoothing rare details or noise. However, the bilateral filter is not efficient to remove the spurious pixels. In practice, the spurious pixels show sharp edges compared to pixels directly surrounding the same. In other words, the bilateral filter holds the spurious pixels even after several iterations of filtering. According to the proposed solution of the present invention, the spurious pixels can be removed from the depth map while maintaining sharp edges of the depth map and smoothing the rare details or noise.
