Project Description

This project is the startup idea of three serial entrepreneurs who want to automate the payment process in canteens. The product can be described as follows: The guest moves his tray under the camera. Our system scans the items on the tray and automatically recognizes and quantifies the products in real time. The names of the products, along with their prices, are then displayed on our dashboard. This enables the system to calculate the total price for the customer, who can then start the checkout process and pay for his products.

Challenge: The system should be able to learn the detection of new products only with a few images (e.g. "continous-learning"). Usually, at least a few hundred images are required to train a neural network to detect a new item and training AI systems with only a few images is still an open research field. Because of that, not many engineers are able to build sufficient systems, which is the reason why this part of the project was the biggest challenge.
This specific feature is needed because a canteen offers new dishes every day. Because of that, there is only a limited amount of time and limited data available to train the object detection system on these new dishes.

Through our experience in building AI systems, we where able to solve the "continous-learning" challenge and deliver an accurate and robust object detection system, together with a responsive web-dashboard to visualize the results.

  • Real time detection

  • Dashboard to show detections, prices etc.

  • Learns to detect new products with only a few images

  • Accurate & robust detections

  • Easy to use (you only need a webcam and a laptop)

Computer Vision

Project Description

In this project, we created a deep learning system to identify metastatic lymph node tissues in digital pathology scans. We also built a dashboard to show the diagnosis of our system, the probability of the diagnosis, and visualizations of why the model made a certain decision. It shows the human doctor what parts of the input image lead to the diagnosis, but also what attributes of the image speak against it. Additionally, it provides the doctor with the top 12 feature maps, along with their relative impact on the diagnosis. With this information in place, the doctor can understand what makes the model think that this person has cancer or not and he can decide with human judgement if he agrees with the diagnosis. It provides him with a fact-based diagnosis to prevent subjective reasoning and to speed up the diagnosis.

We can proudly claim that our system is able to detect lymph node cancer with an accuracy of over 97%, whereas experienced human pathologists can only achieve a performance of 88%. Therefore, this project is a perfect example of the power & the capabilities of deep learning and AI.

  • Outperforms human doctors

  • Enables a fact-based diagnosis

  • Visualize what leads to a diagnosis

  • Shows the probability of a diagnosis

Pneumonia Detection

Computer Vision

Project Description

Here we had to build an AI system to automatically detect and locate lung opacities on chest radiographs (e.g. pneumonia). Pneunomia is one of the top 10 causes of death in the United States and diagnosing the disease is a complex undertaking that previously only highly trained specialists could do. They had to take a patients clinical history, vital signs and laboratory exams into account, which made the whole process very time consuming.
Our system is there to assist the doctor in diagnosing pneunomia. It is able to make accurate & robust diagnoses, only given the chest radiographs. It provides him with a fact-based diagnosis that prevents subjective reasoning and significantly speeds up the time it takes to make a diagnosis.

For this project, we also build a dashboard that has the same capabilities as the dashboard from the "Lymph Node Cancer Detection" project (see section above), but it also displays meta-information about the patient. With it, the doctor can understand why our system made a certain diagnosis and decide with human judgement if he agrees with it.

  • Enables a fact-based diagnosis

  • Shows what leads to a diagnosis

  • Shows the probability of a diagnosis
