  2. Opening (morphology) - Wikipedia

    en.wikipedia.org/wiki/Opening_(morphology)

    Together with closing, the opening serves in computer vision and image processing as a basic workhorse of morphological noise removal. Opening removes small objects from the foreground (usually taken as the bright pixels) of an image, placing them in the background, while closing removes small holes in the foreground, changing small islands of ...

  3. Closing (morphology) - Wikipedia

    en.wikipedia.org/wiki/Closing_(morphology)

    The closing of the dark-blue shape (union of two squares) by a disk, resulting in the union of the dark-blue shape and the light-blue areas. In mathematical morphology, the closing of a set (binary image) A by a structuring element B is the erosion of the dilation of that set,

  4. Structuring element - Wikipedia

    en.wikipedia.org/wiki/Structuring_element

    In mathematical morphology, a structuring element is a shape, used to probe or interact with a given image, with the purpose of drawing conclusions on how this shape fits or misses the shapes in the image. It is typically used in morphological operations, such as dilation, erosion, opening, and closing, as well as the hit-or-miss transform.

  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 ...

  7. Hit-or-miss transform - Wikipedia

    en.wikipedia.org/wiki/Hit-or-miss_transform

    In binary morphology, an image is viewed as a subset of a Euclidean space or the integer grid , for some dimension d.Let us denote this space or grid by E.. A structuring element is a simple, pre-defined shape, represented as a binary image, used to probe another binary image, in morphological operations such as erosion, dilation, opening, and closing.

    Opening price isn’t the same as the closing price from the day before — though both prices show you how a stock is moving — and a couple factors go into setting the opening price.
