Company Background
PrintDreams is a Sweden-based company specialized in developing handheld printers. It is a Gartner Cool Technology Vendor that developed the prototype of the world’s smallest mobile printer, PrintBrush™. It is the world’s first pocket-size inkjet printer with a built-in digital camera. The printer uses PrintDreams’ RMPTTM (Random Moment Printing Technology) that can print in color directly onto virtually any surface.
The Transformative Solution
PrintDreams approached Tech Vedika to build a complete image pre-processing and sensor positioning software that could be used in the mobile printing device to produce a segmented panorama or high-resolution image printing. Tech Vedika developed a solution using computer vision and machine learning that performs the following basic operations from the images captured by the microscopic camera and optical sensors:
Product Features
- Very high accurate 2D position and orientation estimation
 - Halftone concepts based image stitching algorithm
 - Text and graphics information separation in the input image so
 - that text can be treated separately while printing
 - High accurate calibration to get the geometry of the sensors
 

The Results
Tech Vedika developed an advanced image processing and printing
technology which provides the following benefits:
Innovation
- Patentable image pre-processing of the microscope images
 - Patentable high accurate calibration of sensor positions
 - Very fast accurate navigation algorithm using multiple sensors
