Mask R-CNN Image Segmentation - Google Colab

I have rewritten some of the code to match the dataset which is in bounding boxes rather than polygons renamed ballon. I've tried running this on the CPU of my mac 15 inch model with 6-core i7 and it seems to work, but although my CPU is running with fans making sounds as if it is about to take off the terminal always stays at the first epoch. I've run this for about an hour to 90 minutes and the terminal remains at:. When I run the model there it still remains at the first epoch After I'd say at least 20 to 30 minutes.

I downgraded to This leads me to think that the model isn't running and is hanging somehow. You can use Detectron2 to train your model. Here is the link to the colab tutorial. Learn more.

Here is an overview of how you can make your own COCO dataset for instance segmentation. You can install labelme like below or find prebuild executables in the release sectionsor download the latest Windows 64bit executable I built earlier.

When you open the tool, click the "Open Dir" button and navigate to your images folder where all image files are located then you can start drawing polygons. To finish drawing a polygon, press "Enter" key, the tool should connect the first and last dot automatically. When done annotating an image, press shortcut key "D" on the keyboard will take you to the next image. I annotated 18 images, each image containing multiple objects, it took me about 30 minutes. Once you have all images annotated, you can find a list of JSON file in your images directory with the same base file name.

To apply the conversion, it is only necessary to pass in one argument which is the images directory path. The script depends on three pip packages: labelme, numpy, and pillow. Go ahead and install them with pip if you are missing any of them.

After executing the script, you will find a file named trainval.

If you are unfamiliar with the mmdetection framework, it is suggested to give my previous post a try - " How to train an object detection model with mmdetection ". The notebook is quite similar to the previous object detection demoso I will let you run it and play with it. Here is the final prediction result after training a mask RCNN model for 20 epochs, which took less than 10 minutes during training.

The notebook you can run to train a mmdetection instance segmentation model on Google Colab. Go to the mmdetection GitHub repo and know more about the framework. My previous post - How to train an object detection model with mmdetection.

Until recently that is, when libraries for graphics processing units were created to do more than just play games. We can now harness the raw power of thousands of cores to unlock the meanings behind the pictures.

If you want to learn how to convert your own dataset, take a look at the previous article. This time our focus will be to automatically label all the shapes in an image and find out where each of them are, down to the pixel.

These all sound similar and can be confusing at first, but seeing what they do helps clear it up. Below are examples of what kind of information we get from each of the four types. Tasks become more difficult as we move from left to right.

Object recognition tells us what is in the image, but not where or how much. Class segmentation adds position information to the different types of objects in the image. Object detection separates out each object with a rough bounding box. It gives every shape a clear boundary, which can also be used to create the results from the previous three.

A neural network is a collection of connected neurons and each neuron outputs a signal depending on its inputs and internal parameters. When we train a neural network, we adjust neuron internal parameters to create the outputs we expect. CNNs use less parameters and memory than regular neural networks, which allows them to work on much larger images than a traditional neural network.

Plain CNNs are good at object recognition, but if we want to do object detection we need to know where things are. R-CNNs are able to draw bounding boxes around the objects they find.

Those regions are then used as bounding boxes if an object is found inside them. It adds an additional branch to the network to create binary masks which are similar to the ones we make when annotating images.

You can find more information on each of them in the References and Resources below. But before we can benefit from having things set up automatically for us, first we need to get our host system ready.

Training your own dataset with mask scoring RCNN

After installing Ubuntu First of all simply clone the following repository, it is a demo of an individual class segmentation. You will simply need to do the following:. On top of all, a starting weight is needed, of course you can write your own random initializer, but in our case we decided to simply pick the default.

To get the weight, you can get it from my drive. After cloning the repository, you should get the following structure. All modifications to be made are within the train. From line 65 till 74, simply modify the category variable and the class names for it to match your dataset here is the what is originally written :.

You will simply need to change the parameters written on this part of train. Wrapping up, after putting your own dataset in the dataset folder check inside the folders to know what to put in and the format of itrunning the following command starts the training:.

You should get this illustration after entering the command:. Thanks a bunch for reading and stay tuned for further interesting articles!

Using Mask R-CNN you can automatically segment and construct pixel-wise masks for every object in an image. Is it possible to generate a mask for each object in our image, thereby allowing us to segment the foreground object from the background?

Explaining the differences between traditional image classification, object detection, semantic segmentation, and instance segmentation is best done visually. When performing traditional image classification our goal is to predict a set of labels to characterize the contents of an input image top-left. Object detection builds on image classification, but this time allows us to localize each object in an image.

The image is now characterized by:. An example of semantic segmentation can be seen in bottom-left. Semantic segmentation algorithms require us to associate every pixel in an input image with a class label including a class label for the background.

While semantic segmentation algorithms are capable of labeling every object in an image they cannot differentiate between two objects of the same class. This behavior is especially problematic if two objects of the same class are partially occluding each other — we have no idea where the boundaries of one object ends and the next one begins, as demonstrated by the two purple cubes, we cannot tell where one cube starts and the other ends.

Instance segmentation algorithms, on the other hand, compute a pixel-wise mask for every object in the image, even if the objects are of the same class label bottom-right.

Here you can see that each of the cubes has their own unique color, implying that our instance segmentation algorithm not only localized each individual cube but predicted their boundaries as well. ROI Pooling works by extracting a fixed-size window from the feature map and using these features to obtain the final class label and bounding box. The primary benefit here is that the network is now, effectively, end-to-end trainable:.

While the network is now end-to-end trainable, performance suffered dramatically at inference i. As a whole, the Faster R-CNN architecture is capable of running at approximately FPS, a huge step towards making real-time object detection with deep learning a reality.

He et al. Here you can see that we start with our input image and feed it through our Mask R-CNN network to obtain our mask prediction. The predicted mask is only 15 x 15 pixels so we resize the mask back to the original input image dimensions.

Finally, the resized mask can be overlaid on the original input image. Before we begin, ensure that your Python environment has OpenCV 3. If you want to be up and running in 5 minutes or less, you can consider installing OpenCV with pip. If you have some other requirements, you might want to compile OpenCV from source.
