Abstract:
A learning-based visual attention prediction method is disclosed. The method includes a correlation relationship between the fixation density and at least one feature information being learned by training, followed by a test video sequence of test frames being received. Afterward, at least one tested feature map is generated for each test frame based on the feature information. Finally, the tested feature map is mapped into a saliency map, which indicates the fixation strength of the corresponding test frame, according to the correlation relationship.
Abstract:
A photovoltaic device is provided that includes a semiconductor substrate including a p-n junction with a p-type semiconductor portion and an n-type semiconductor portion one on top of the other. A plurality of patterned antireflective coating layers is located on a p-type semiconductor surface of the semiconductor substrate, wherein at least one portion of the p-type semiconductor surface of the semiconductor substrate is exposed. Aluminum is located directly on the at least one portion of the p-type semiconductor surface of the semiconductor substrate that is exposed.
Abstract:
A method of forming a low-k dielectric layer or film includes forming a porous low-k dielectric layer or film over a wafer or substrate. Active bonding is introduced into the porous low-k dielectric layer or film to improve damage resistance and chemical integrity of the layer or film, to retain the low dielectric constant of the layer and film after subsequent processing. Introduction of the active bonding may be accomplished by introducing OH and/or H radicals into pores of the porous low-k dielectric layer or film to generate, in the case of a Si based low-k dielectric layer or film, Si—OH and/or Si—H active bonds. After further processing of the low-k dielectric film, the active bonding is removed from the low-k dielectric layer or film.
Abstract:
A method for fabricating an organic light emitting diode and a device thereof are provided. The method includes: providing a substrate; dispensing to the substrate a second organic molecule solution resulting from dissolving a second organic molecule in a solvent; applying the second organic molecule solution to a surface of the substrate so as to form a wet film layer; and heating the wet film layer by a heating unit to remove the solvent therefrom and thereby form a second organic molecule film. The method is effective in fabricating a uniform multilayer structure for use in fabrication of large-area photoelectric components.
Abstract:
A method for improving an optical sensor is disclosed, which includes the following steps: providing an optical sensor; acid-treating the surface of the optical sensor; forming a thin metal film on the acid-treated surface of the optical sensor; and plasma-modifying the thin metal film on the optical sensor. The aforesaid method is to clean the surface of the optical sensor and then to improve the hydrophilicity thereof by acid treatment. The thin metal film subsequently formed has good flatness and improved adhesion to the optical sensor. Once the optical sensor has the improved hydrophilicity, the plasma modification is performed to further improve optical performance of the optical sensor.
Abstract:
A method of printing geometric figures recalculates and recombines coordinates of the scan lines or poly scan lines to transform into polygonal geometric figures with less output the data and command length, thereby increasing the printing speed of a printer. The method also can be applied to any geometric figures or texts constructing by the scan lines or the poly scan lines.
Abstract:
A process for producing hollow polyamide filaments having at least one continuous void that adds to a fiber-forming polyamide from about 0.05% to about 5% of a triazine compound prior to extrusion of fiber. The process results in a greater closure of voids and larger void space than when the triazine compound is not used.
Abstract:
Claimed are a method of making a direction indicating carpet, useful in temporarily unlighted building hallways and rooms. Symbols are tufted into the carpet using zinc sulfide copper activated pigments in concentration of 2% in the fiber.
Abstract:
A method for producing carpet yarn produces yarn having substantial soil hiding, soil repelling and resistance to staining with acid dye characteristics. The yarn is made by forming at least one hollow trilobal fiber from a molten nylon polymer having an amine end group level below about 25 meq/kg, the fiber having a modification ratio of about 2 and a void volume of at least 3%; quenching the formed fiber sufficiently to solidify the molten nylon; immediately after quenching, at a yarn speed of at least 300 mpm, finishing the fiber with spin finish containing fluorochemical; fully drawing the finished fiber; texturing the finished yarn by a hot fluid texturing process; and subsequently, applying to the textured yarn a sulfonated stainblocker, the stainblocker being heated to at least 50.degree. C. and applied while the fiber temperature is at least about 100.degree. C. in the stainblocker application step. The yarn travels at a rate sufficient to permit fixation of the stainblocker while minimizing penetration of stainblocker into the yarn.
