    摘要: A “Text Rectifier” provides various techniques for processing selected regions of an image containing text or characters by treating those images as matrices of low-rank textures and using a rank minimization technique that recovers and removes image deformations (e.g., affine and projective transforms as well as general classes of nonlinear transforms) while rectifying the text or characters in the image region. Once distortions have been removed and the text or characters rectified, the resulting text is made available for a variety of uses or further processing such as optical character recognition (OCR). In various embodiments, binarization and/or inversion techniques are applied to the selected image regions during the rank minimization process to both improve text rectification and to present the resulting images of text to an OCR engine in a form that enhances the accuracy of the OCR results.

    摘要: The present invention provides a method of passivating a semiconductor device having a capping layer formed thereover, comprising: (1) subjecting the semiconductor device to a high pressure within a pressure chamber and (2) exposing the semiconductor device to a passivating gas. The high pressure causes the passivating gas, such as a deuterated passivating gas, to penetrate the capping layer and thereby passivate the semiconductor device. The method provided by the present invention is, therefore, particularly useful in those instances where a final passivation step is desired after the formation of the capping layer. It is believed that the hydrogen isotope bonds to dangling bond sites within the semiconductor device, which are most often present at a silicon/silicon dioxide interface. Further, because of their larger mass, these hydrogen isotope atoms are not easily removed by electron flow during the operation of the device as is the case with the lighter hydrogen atoms.
