Computer vision-based app to change colors

We’ve created a simple solution that changes the colors of the chosen objects using computer vision.

About a Project

Create an open-source app based on Swift and OpenCV that uses computer vision to track objects and change their colors.

Project idea

Detecting the planes where to change colors

Integrating nine popular colors

Implementing the ability to edit color saturation

Project challenges

Our specialists worked on report system behavior and complex algorithms that help to generate report results. We've completely redesigned the app, created a fully operational admin panel, developed iOS and Android apps.


Our team developed a complex search system and created video players for iOS and Android. We’ve designed a completely new UI, built iOS, reengineered Android and Android TV apps, and partially moved to GraphQL.

How does computer vision work?
Computer vision uses pictures and videos to understand a real-world scene.
Computer vision can
  • Identify objects on images or videos.
  • Track things that are moving.
  • Measure the real-world size or estimate the distance from the camera.
  • Detect objects even if they change size or orientation.
  • Classify things on the video or photo.
  • Image classification. Receiving many examples of the image class for computer vision machine learning.
  • Object detection. Defining the objects in the image and labeling them.
  • Object tracking. Following one or more moving objects in the scene.
  • Semantic segmentation. Dividing the entire picture into groups of pixels that can be labeled and classified.

Main features of the project

A powerful backend of the app has transformed into two main features.

Changing object color

The main feature of ColorDetection is changing the color of the chosen object in a real-time mode. The user can choose from nine colors. It’s required to tap on the item and pick the color from the list.



After picking the new color, the user can change the saturation of the picked color. Also, it’s possible to set the height, volume, and space of the object.
