Vectorization (or image tracing) is the conversion
of raster images into vector graphics.
Raster images (JPEG, BMP, GIF, TIFF, PNG) are made up of a limited number of pixels. When enlarged, raster image reveals the pixels and drastically reduces the quality.
Vector images are built up of lines and colour surfaces that are stored in files by mathematical equations. Vector graphics applications use these equations to rebuild the image on the screen. Zooming in on a vector image, regardless of size, every detail is preserved.

Because the graphics libraries of vectorial apps contain a limited number of equations,
vector graphics cannot retrieve all the details of a complex raster image. Transforming
a photo into a vector image gives it the appearance of a drawing. In this regard,
vectorization is a process of stylization; it can be useful for making sketches or drawings
by photos, logo or icon reproduction from scanned images, and so on. The images thus obtained
can be used to print large banners and posters, for embroidery, for etching operations, or can
be cut-ready for signs, vehicles, clothing, or other objects.
Most vector graphics apps have auto-trace functions, but the results are often unsatisfactory. On the other hand, manual vectorization performed by a skilled operator provides quality but is laborious. Our method uses an original application that removes insignificant details and divides the source image by appropriate zoning. Areas that can be processed automatically are separated from those requiring manual intervention. Spectacular results can be obtained in a short time, with minimum effort.
