The Hough transform [3] can be used to detect lines and the output is a parametric description of the lines in an image, for example ρ = r cos(θ) + c sin(θ). [1] If there is a line in a row and column based image space, it can be defined ρ, the distance from the origin to the line along a perpendicular to the line, and θ, the angle of the perpendicular projection from the origin to the ...
This is an incomplete list of notable applications (apps) that run on iOS where source code is available under a free software/open-source software license.Note however that much of this software is dual-licensed for non-free distribution via the iOS app store; for example, GPL licenses are not compatible with the app store.
Screenshot of an iOS 17 home screen, displaying various built-in apps. Apple Inc. develops many apps for iOS that come bundled by default or installed through system updates. . Several of the default apps found on iOS have counterparts on Apple's other operating systems such as macOS, iPadOS, watchOS, and tvOS, which are often modified versions of or similar to the iOS applicati
Use of the Hough transform on noisy images is a very delicate matter and generally, a denoising stage must be used before. In the case where the image is corrupted by speckle, as is the case in radar images, the Radon transform is sometimes preferred to detect lines, because it attenuates the noise through summation.

An edge in an image may point in a variety of directions, so the Canny algorithm uses four filters to detect horizontal, vertical and diagonal edges in the blurred image. The edge detection operator (such as Roberts, Prewitt, or Sobel) returns a value for the first derivative in the horizontal direction (G x) and the vertical direction (G y ...
Apple released iPhone OS 2.0 in July 2008 for the iPhone, together with the App Store, officially introducing third-party app development and distribution to the platform. The service allows users to purchase and download new apps for their device through either the App Store on the device, or through the iTunes Store on the iTunes desktop ...
