There is more simple architecture of RNN with tensorflow but result on russian traffic dataset is bad (about 70% of recognized images with 100000 epoch – training time – about 15 hours). Anyway I will show python program for information. """ modification of traffic_ru dataset with image preprocession (make YUV mormalized images) from http://jokla.me/robotics/traffic-signs/...
We have prepared all necessary files after implementation of part 1 and part 2 works. Lets start procedure of learning with tensorflow. TF model part taken at this link (Jiovanny Claudio). Jiovanny gave very good explanation of Tensorflow model which have used for deep learning. I have made some corrections in model for correct...
I have described bad attempts to train RNN with Russian Traffic dataset before – here for example. To solve this problem first I have sorted all images into classes to it’s own directory and found that quality of images is very bad: 1. there is a lot of images which can’t recognize by human...
There is some approaches how to detect traffic signs (TS) at the image (some info available here and here - (thanks to Miki) and here): 1. Color-based detection 2. Shape-based detection 3. Pattern detection and recognition Colors at the image could be different – depends of quality, camera sensor, backligth etc. If You want to use...
Tensorflow has very good example how to use pretrained model with Android devices. https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android Only choose Your machine environment and demo example will be installed. I have Android Studio with standart Gradle project. Thats why need only copy this folder (/tensorflow/examples/android) from tensorflow github batch to my folder with Android workspaces. after tha need...
Используя как основу статью Валида Абдулы https://medium.com/@waleedka/traffic-sign-recognition-with-tensorflow-629dffc391a6 Попробуем сделать рабочую программу распознавания дорожных знаков. Сначала бельгийских, затем нашенских. Ссылка на скачивание российского датасета в предыдущих постах… Бельгийский датасет в примерах. С учетом, что прога писалась для 0.12 версии Tensorflow, ее надо немного модифицировать и поставить необходимые библиотеки. Прога для Python2.7 и tensorflow 1.1...
