Image Processing and Computer Vision. Object recognition is a computer vision technique for identifying objects in images or videos. Object recognition is a key output of deep learning and machine learning algorithms. When humans look at a photograph or watch a video, we can readily spot people, objects, scenes, and visual details. The goal is to teach a computer to do what comes naturally to humans: to gain a level of understanding of what an image contains. Object recognition is a key technology behind driverless cars, enabling them to recognize a stop sign or to distinguish a pedestrian from a lamppost.

How to Implement Artificial Intelligence for Solving Image Processing Tasks

Occlusions and disocclusions are essential cues for human perception in understanding the layout of a scene. By analyzing how some parts of the scene go out of the sight occluded and new parts appear disoccluded , one can infer the topology of the objects in it. Since the scene geometry and its dynamics induce this phenomena, they are fundamental cues in computer vision and video processing tasks such as visual exploration, object recognition, activity recognition, tracking and video compression. In this thesis, we first introduce three methods to detect occlusions in an image sequence: 1 a motion segmentation algorithm which partitions an oversegmented image into two parts: a region on which optical flow is expressed with a piecewise-constant field and occluded regions where flow is not defined, 2 an optical flow estimation method which additionally detects occlusions modeling them as sparse subset of the image domain, and 3 a saliency detection algorithm which detects the parts of the image domain whose motion is inconsistent with the camera motion. In the second part of the thesis, we show that the problem of object detection in a video can be cast as an unsupervised segmentation scheme using occlusion cues and solved using convex optimization for an unknown number and geometry of objects in the scene.

Large scale object detection

It seems that you're in Germany. We have a dedicated site for Germany. Editors: Jiang , X. This book discusses recent advances in object detection and recognition using deep learning methods, which have achieved great success in the field of computer vision and image processing.

DetReco: Object-Text Detection and Recognition Based on Deep Neural Network

Machines can be taught to interpret images the same way our brains do and to analyze those images much more thoroughly than we can. When applied to image processing, artificial intelligence AI can power face recognition and authentication functionality for ensuring security in public places, detecting and recognizing objects and patterns in images and videos, and so on. In this article, we talk about digital image processing and the role of AI in it. We describe some AI-based image processing tools and techniques you may use for developing intelligent applications. We also take a look at the most popular neural network models used for different image processing tasks.

Deep learning-based object detection method has been applied in various fields, such as ITS intelligent transportation systems and ADS autonomous driving systems. Meanwhile, text detection and recognition in different scenes have also attracted much attention and research effort. The proposed method is composed of object-text detection network and text recognition network. We combine the datasets of general objects and texts together to train the networks. At test time, the detection network detects various objects in an image. Then, the text images are passed to the text recognition network to derive the text contents. The experiments show that the proposed method achieves

Computer vision is an interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering , it seeks to understand and automate tasks that the human visual system can do. Computer vision tasks include methods for acquiring , processing , analyzing and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e. This image understanding can be seen as the disentangling of symbolic information from image data using models constructed with the aid of geometry, physics, statistics, and learning theory. The scientific discipline of computer vision is concerned with the theory behind artificial systems that extract information from images. The image data can take many forms, such as video sequences, views from multiple cameras, multi-dimensional data from a 3D scanner, or medical scanning device.

Object Detection from the Video Taken by Drone via Convolutional Neural Networks

The aim of this research is to show the implementation of object detection on drone videos using TensorFlow object detection API. The function of the research is the recognition effect and performance of the popular target detection algorithm and feature extractor for recognizing people, trees, cars, and buildings from real-world video frames taken by drones. An object recognition system uses a priori known object model to find real-world pairs from images of the world [ 1 , 2 ]. Human beings can perform object detection very easily and effortlessly, but this problem is amazingly difficult for machines.

 - Мидж торопливо пересказала все, что они обнаружили с Бринкерхоффом. - Вы звонили Стратмору. - Да. Он уверяет, что в шифровалке полный порядок. Сказал, что ТРАНСТЕКСТ работает в обычном темпе.

 Танкадо не посмеет этого сделать! - воскликнула.  - Уничтожить всю нашу секретную информацию? - Сьюзан не могла поверить, что Танкадо совершит нападение на главный банк данных АНБ. Она перечитала его послание.

Вот бы побывать здесь вместе со Сьюзан. - И, разумеется, Христофора Колумба? - просиял лейтенант.  - Он похоронен в нашем соборе.

 Пока не везет.  - Она вздохнула.  - Быть может, придется ждать, пока Дэвид не найдет копию Танкадо. Стратмор посмотрел на нее неодобрительно. - Если Дэвид не добьется успеха, а ключ Танкадо попадет в чьи-то руки… Коммандеру не нужно было договаривать.

 И. - Итак, ТРАНСТЕКСТ вскрывает один шифр в среднем за шесть минут. Последний файл обычно попадает в машину около полуночи. И не похоже, что… - Что? - Бринкерхофф даже подпрыгнул.

Где ваш пистолет. Мысли Стратмора судорожно метались в поисках решения. Всегда есть какой-то выход. Наконец он заговорил - спокойно, тихо и даже печально: - Нет, Грег, извини. Я не могу тебя отпустить.

В свете ламп дневного света он сумел разглядеть под красноватой припухлостью смутные следы каких-то слов, нацарапанных на ее руке. - Но глаза… твои глаза, - сказал Беккер, чувствуя себя круглым дураком.  - Почему они такие красные. Она расхохоталась.

Сьюзан была озадачена. - Это по-латыни, - объяснил Хейл.  - Из сатир Ювенала. Это значит - Кто будет охранять охранников?.

Но директор давным-давно взял за правило умывать руки, позволяя своим умным сотрудникам заниматься своим делом, - именно так он вел себя по отношению к Тревору Стратмору. - Мидж, тебе отлично известно, что Стратмор всего себя отдает работе.
