Well done - several cosmetic fixes

| Finally we will assign random persistent color to each detection class and draw a bounding box around the object. We filter out low confidence predictions using `score` output. |
| verts = np.asanyarray(points.get_vertices()).view(np.float32).reshape(-1, W, 3) # xyz | ||
| ``` | ||
|
|
||
| This allows us to query XYZ coordinates of each detected object and to seperate individual coordinates (in meters): |

| ## Part 3 - Deploying TensorFlow model using OpenCV | ||
|
|
||
| While TensorFlow is convinient to install and use, it is not as convinient as OpenCV. OpenCV is ported to most platforms and is well optimised for various types of CPUs. It also comes with built-in DNN module capable of loading and using TensorFlow models without having TensorFlow (or its dependencies) installed. |
| Unet offers significant advantages compared to classic autoencoder architecture, improving edge fidelity (see image below). | ||

| very good at detecting more and more features, the first few layers of a convolution network capture a very small semantic information and lower level | ||
| features, as you go down these features become larger and larger, but when we throw away information the CNN | ||
| knows only approximate location about where those features are. | ||
| When we upsample we get the lost information back (by the concatination process) |
| #### Data Augmentation | ||
| To help the neural network learning image features we decide to crop input images into tiles of 128x128 pixels. | ||
|
|
||
| Each ground truth image has a corressponding depth and infrared image. Given that, the dataset is augmented as following: |
