摘要:
A multilevel texture mapping process for a 3D model maps different perspective images onto a 3D model. The textures mapped to the 3D model are processed from image level to texture level, then to pixel level, hence, the method eases the edge appearance problem at the boundary where neighboring images are stitched together caused by different lighting and viewing parameters. The result shows that the smooth transition between neighboring textures provides better visual quality than just blending the boundary where neighboring images are stitched.

A depth image acquiring device is provided, which includes at least one projecting device and at least one image sensing device. The projecting device projects a projection pattern to an object. The image sensing device senses a real image. In addition, the projecting device also serves as a virtual image sensing device. The depth image acquiring device generates a disparity image by matching three sets of dual-images formed by two real images and one virtual image, and generates a depth image according to the disparity image. In addition, the depth image acquiring device also generates a depth image by matching two real images, or a virtual image and a real image without verification.

A fixing structure including a metal housing and a fixing base is disclosed. The housing has a carrying plane and the fixing base having a first contact end and, opposite, a second contact end is disposed on the housing. The perpendicular distance from the first contact end to the carrying plane is greater than that from the second contact end to the carrying plane. A wireless transmission device is disposed on the fixing base and in contact with the first contact end and the second contact end, so that a perpendicular distance from an antenna end of the wireless transmission device to the carrying plane is greater than a perpendicular distance from a fixed end of the wireless transmission device to the carrying plane. Therefore, a relatively great distance is kept between the antenna end and the housing for preventing the antenna end from being interfered by the metal housing.

Alcohols effectively solidified by using various hydroxides in combination with different cellulose compounds, and also, alcohols effectively solidified by using various cyanoacrylate monomers in combination with different cellulose compounds. The cyanoacrylate reactions complete very rapidly in seconds and generally release large amounts of heat. Suitable additives are added to slow down the reactions for gradual heat dissipation and easy manipulation. The alcohol liquids can be solidified as well. Solid alcohol blocks and alcohol gels may be shelled by dipping into cyanoacrylate and coating them with a cyanoacrylate shell for long term storage.

摘要:
A method to form a better quality of an alignment pattern includes several steps, first starts from forming a polysilicon layer on a semiconductor substrate. Next, most of a central portion of the polysilicon layer is removed to expose the substrate. Then, an oxide layer is formed over the substrate and is patterned to form an opening, which exposes the substrate. A W layer is deposited over the substrate and is planarized by WCMP process to form a W plug inside the opening. A metal layer is formed over the substrate. The alignment mark pattern is formed on the metal layer.
摘要:
A printable reusable gel film formed of a polyvinyl acetic acid (PVA) or polyvinyl alcohol (PVOH) layer, a carrier layer, an acrylic adhesive layer, an elastic plastic sheet layer, an elastomer layer and a strippable plastic film is disclosed. The polyvinyl acetic acid (PVA) or polyvinyl alcohol (PVOH) layer and the carrier layer each have a protruding portion for guidance in printing. The strippable plastic film has perforations for ventilation to prevent accumulation of air during printing, assuring a high level of printing quality.
