6.0.1 Improved Network Traininng (2020-04-20)

• Retraining of CNN with slightly improved image classification

6.0.0 Tensorflow 2.1 (2020-04-18)

• Updated to Tensorflow 2.1
• additional export to TF-Lite Version (.tflite)
• Training with new picture from iobroker users

5.0.0 Current Version - Tensorflow 2.0

• Training with new picture from iobroker users
• Removal of standalone server - (included in main project)Training of additional digital number (provided from iobroker users)

4.1.0 Current Version - Tensorflow 2.0

• Training of the network with a second type of analog counters (different pointer)

4.0.0 Current Version - Tensorflow 2.0

• Image processing changed to Pillow (remove OpenCV)
• Usage of Tensorflow 2.0 for training

4.0.0 Change to Pillow Image Library

• Image processing changed to Pillow (remove OpenCV)

3.0 Version number skipped due to consistency with other programm part

2.1.0 Handle periodic nature with trigonometric angle functions

• Increased precision by handwise relabeling of the input
• Addtional training images from different illuminatin (ESP32-CAM)

2.0.0 Handle periodic nature with trigonometric angle functions

• Adaption of neural network output to sinus and cosinus of pointer angle. Calculation of angle by arctan as unique function of full roation --> removal incontinuity at output neuron.

1.x.y Initial Version

• Handling of periodic nature with differnt non continious strategies (switching of output neurons, introduction of periodic loss instead of mean square, ...)
• Improve learning by stepwise training strategie and adaption of neutral network structure / size neuron
