With over 20 years of experience in data science and application development, Contata specializes in leveraging Azure Cognitive Services to deliver cutting-edge solutions to businesses to help them analyze large volumes of data, recognize patterns, and make predictions in real-time.

Recently, we were approached by an event organization company that organizes events like paid dinners, charity lectures, and shows where buyers got to meet and listen to prominent guests like political leaders, celebrities, etc. Everything was working fine for the company, but there was one major problem: the events were attracting a much larger audience than anticipated and the company was struggling to keep track of the attendees. Because there was a large influx of audience, using the traditional method of managing attendance, which involved checking attendees’ names against a list of registered attendees, was not possible as it was a very time-consuming and error-prone process.

The company needed a more efficient and reliable way to monitor attendance and see if any special guests were attending the events. It was looking for a low-cost and easy-to-maintain attendance system that could help them to not only track people attending their events but provide critical insights into how successful these events were. Something that could observe the mood of the audience and measure the overall response at the events.

This is where Contata came to the rescue! Our team of experienced app developers leveraged Azure Cognitive services to provide an appropriate solution to the event management company. We deployed Azure’s Face Recognition model under Computer Vision to detect faces of people entering the events. A gender detection model was placed on top of the Face API that supported gender classification with a support vector machine (SVM) to classify the audience based on their gender. The model was also programmed to detect if there were any stage or group entries to the events.

The captured faces were matched with an existing face directory of local and national celebrities to see if there was a special guest in the events, and if a match was found, the application immediately sent an alert to the event organizer. Faces captured at different moments of the events were captured and passed to a pre-trained mood detector SVM to detect a person’s mood.

The company was extremely happy with the results as it was able to better manage the attendance at their events without manual handling and capture quality data for analysis.
