Features from accelerated segment test FAST is a corner detection method, which could be used to extract feature points and later used to track and map objects in many computer vision tasks.

Adaptive and Generic Corner Detection Based on the Accelerated Segment Test

The efficient detection of interesting features is a crucial step for various tasks in Computer Vision. Corners are favored cues due to their two dimensional constraint and fast algorithms to detect them. Recently, a novel corner detection approach, FAST, has been presented which outperforms previous algorithms in both computational perfor-mance and repeatability. We will show how the accelerated segment test, which underlies FAST, can be significantly improved by making it more generic while increasing its performance. We do so by finding the opti-mal decision tree in an extended configuration space, and demonstrating how specialized trees can be combined to yield an adaptive and generic accelerated segment test. The resulting method provides high perfor-mance for arbitrary environments and so unlike FAST does not have to be adapted to a specific scene structure. We will also discuss how differ-ent test patterns affect the corner response of the accelerated segment test.

Corner detection and sorting method based on improved Harris algorithm in camera calibration. In traditional Harris corner detection algorithm , the appropriate threshold which is used to eliminate false corners is selected manually. In order to detect corners automatically, an improved algorithm which combines Harris and circular boundary theory of corners is proposed in this paper. After detecting accurate corner coordinates by using Harris algorithm and Forstner algorithm , false corners within chessboard pattern of the calibration plate can be eliminated automatically by using circular boundary theory. Moreover, a corner sorting method based on an improved calibration plate is proposed to eliminate false background corners and sort remaining corners in order. Experiment results show that the proposed algorithms can eliminate all false corners and sort remaining corners correctly and automatically.

An efficient and geometric-distortion-free approach, namely the fast binary robust local feature FBRLF , is proposed. The FBRLF searches the stable features from an image with the proposed multiscale adaptive and generic corner detection based on the accelerated segment test MAGAST to yield an optimum threshold value based on adaptive and generic corner detection based on the accelerated segment test AGAST. To overcome the problem of image noise, the Gaussian template is applied, which is efficiently boosted by the adoption of an integral image.

 Ну что, вы решили. Я ее убиваю. Стратмор мгновенно взвесил все варианты. Если он позволит Хейлу вывести Сьюзан из шифровалки и уехать, у него не будет никаких гарантий.

Я тебе очень благодарен. - Не стоит благодарности.  - Она улыбнулась и села напротив шефа. Стратмор был крупным кряжистым мужчиной, чье невыразительное лицо скрывало присущие ему решительность, настойчивость и неизменное стремление к совершенству. Серые глаза светились уверенностью, с которой сочеталась профессиональная скрытность, но сегодня в них проглядывали беспокойство и нерешительность.

Нуматек - богатая фирма, наиболее вероятный победитель аукциона. Ни у кого не вызовет подозрений, если ключ попадет именно к. И что особенно удачно - эту компанию меньше всего можно было заподозрить в том, что она состоит в сговоре с американским правительством. Токуген Нуматака воплощал старую Японию, его девиз - Лучше смерть, чем бесчестье. Он ненавидел американцев. Ненавидел американскую еду, американские нравы, но более всего ему было ненавистно то, что американцы железной хваткой держали мировой рынок компьютерных программ.

Теоретически постоянная мутация такого рода должна привести к тому, что компьютер, атакующий шифр, никогда не найдет узнаваемое словосочетание и не поймет, нашел ли он искомый ключ. Вся эта концепция чем-то напоминала идею колонизации Марса - на интеллектуальном уровне вполне осуществимую, но в настоящее время выходящую за границы человеческих возможностей. - Откуда вы взяли этот файл? - спросила .

 Ой, дорогие мои… - сказала вдруг Соши. Она открыла на экране второе окно и просматривала остальную часть документов Лаборатории вне закона.

 Северная Дакота. Разумеется, это кличка. - Да, но я на всякий случай заглянул в Интернет, запустив поиск по этим словам.

Однажды вечером на университетском представлении Щелкунчика Сьюзан предложила Дэвиду вскрыть шифр, который можно было отнести к числу базовых. Весь антракт он просидел с ручкой в руке, ломая голову над посланием из одиннадцати букв: HL FKZC VD LDS В конце концов, когда уже гасли огни перед началом второго акта, его осенило.

    We will show how the accelerated segment test, which underlies FAST, can be significantly improved by making it more generic while increasing its performance​.
