I should note that this is completely empirical and could easily change if the color balance is different in another set of images. I multiplied the result by 0.25 to bring it to between 0 and 1 so it could be thresholded to get the purple tissue region. (4) Divide the red channel by the green channel to enhance the region that I’m assuming is the purple area. (3) The colored region is subtracted from the compete tissue area to get the black tissue region. I chose the blue channel since it seemed to give the highest contrast between the colored regions and the black areas. (2) Mask the blue channel and threshold to find the colored region. (1) Combine the RGB channels in a grayscale image, invert it and threshold to find the complete tissue region. I’ve attached a pipeline that seems to work on the images that you provided, but I can’t guarantee its effectiveness on all the images that you throw at it. For example, what you define as “purple”, “blue” and “black” may be different from what I would define those colors to be. Windows 8 is known for being the shortest-supported version of Windows, having had its support end on Janu(to regain support, users are recommended to upgrade to Windows 8.1, which can be done on this version without an installation disc).Histological images can be difficult to work with, since color is a very subjective quantity that varies according to not only the imaging device but also the observer. However, it received a mixed reception, with many criticizing it as being unintuitive compared to its predecessor and questioning Microsoft's push to expand the Windows line to touchscreen devices. Windows 8 was released on October 26, 2012, and introduced features such as the new Start screen, the Charms, apps, and touchscreen support for devices such as the new Surface tablet. Notably, this logo ditched the flag design that had been used since 2001, as well as the three-dimensional Aero theme, replacing it with a simple window tilted to the left, designed by Pentagram. This logo was unveiled on Windows 8 Consumer Preview, released in February 29, 2012. Microsoft overhauled their logo again to fit in with the new Metro design language on Windows 8, which removed the colors to become all blue and introduced a slightly modified Segoe font. Cowles, art director at Microsoft from 1991 to 1994, cites himself as designer of the original Windows flag, under the supervision of Boettcher and Julie Wong. On Twitter, Microsoft cites Jeff Boettcher as the designer of the original Windows flag. Support for the Windows 3.1x line of operating systems ended on December 31, 2001, except for WFW 3.11 embedded, in which support ended on November 1, 2008. This logo also would have a trail behind it. The rest of the 3.1x series included Windows 3.11, Windows 3.2 and Windows for Workgroups, where slight changes were made to the colors of the logo. The iconic four colored Windows logo was introduced with Windows 3.1. Windows 3.1 was an updated version of Windows 3.0, with several enhancements to the still DOS-based platform, including improved system stability, expanded support for multimedia, Truetype fonts, and workgroup networking.
