  2. Kernel (image processing) - Wikipedia

    en.wikipedia.org/wiki/Kernel_(image_processing)

    In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more. This is accomplished by doing a convolution between the kernel and an image .

  3. Visual masking - Wikipedia

    en.wikipedia.org/wiki/Visual_masking

    Visual masking involves surrounding a target image (here, the word "radio") with another image. Visual masking is a phenomenon of visual perception. It occurs when the visibility of one image, called a target, is reduced by the presence of another image, called a mask. [1] The target might be invisible or appear to have reduced contrast or ...

  4. Mask (computing) - Wikipedia

    en.wikipedia.org/wiki/Mask_(computing)

    In computer graphics, when a given image is intended to be placed over a background, the transparent areas can be specified through a binary mask. [1] This way, for each intended image there are actually two bitmaps: the actual image, in which the unused areas are given a pixel value with all bits set to 0s, and an additional mask, in which the ...

  5. Top-hat transform - Wikipedia

    en.wikipedia.org/wiki/Top-hat_transform

    In mathematical morphology and digital image processing, a top-hat transform is an operation that extracts small elements and details from given images.There exist two types of top-hat transform: the white top-hat transform is defined as the difference between the input image and its opening by some structuring element, while the black top-hat transform is defined dually as the difference ...

    Enclosed C or circled Latin C (Ⓒ or ⓒ) is a typographical symbol. As one of many enclosed alphanumerics, the symbol is a "C" within a circle. Encodings

  7. Multiple patterning - Wikipedia

    en.wikipedia.org/wiki/Multiple_patterning

    The mask cost strongly benefits from the use of multiple patterning. The EUV single exposure mask has smaller features which take much longer to write than the immersion mask. Even though mask features are 4x larger than wafer features, the number of shots is exponentially increased for much smaller features.

  8. Robinson compass mask - Wikipedia

    en.wikipedia.org/wiki/Robinson_Compass_Mask

    In image processing, a Robinson compass mask is a type of compass mask used for edge detection. It has eight major compass orientations, [ 1 ] each will extract the edges in respect to its direction. A combined use of compass masks of different directions could detect the edges from different angles.

  9. Integrated circuit layout design protection - Wikipedia

    en.wikipedia.org/wiki/Integrated_circuit_layout...

    The United States Code (USC) defines a mask work as "a series of related images, however fixed or encoded, having or representing the predetermined, three-dimensional pattern of metallic, insulating, or semiconductor material present or removed from the layers of a semiconductor chip product, and in which the relation of the images to one ...
