Система диагностики заболеваний листьев растений по фотоизображениям, полученным с помощью БПЛА

Спб.: ПОЛИТЕХ-ПРЕСС
Представлен новый способ цифровой обработки изображений для обнаружения болезней растений по цифровым изображениям в видимом спектре. Были выбраны методы, которые исследуют видимые симптомы в листьях растениях.

Use of an extended set of features Haralick in the diagnosis of plant diseases on leaf images

Vibroengineering PROCEDIA
Proposed method based on fuzzy logic, including the operation of calculating the 36 key parameters of the R, G, B, RG, RB, GB color components of the original RGB color space images of plant leaves and the GLCM adjacency matrix, forming fuzzy conclusions about the type of plant disease, defusing using threshold binarization and majority voting on 6 parameters.

Комплексные методы обнаружения железнодорожных путей как основа обнаружения препятствий

Железнодорожный транспорт
Предложены подходы для обнаружения железнодорожного пути при движении беспилотного локомотива, позволяющие повысить точность и достоверность информации путем применения классических методов компьютерного зрения, нейронных сетей, электронной карты с последующим комплексированием данных от нескольких источников. Учтено негативное влияние плохих погодных условий на качество изображений и предложено применение алгоритмов AGC и CLAHE для своевременного улучшения качества изображений.
