Sample Raster to Vector Conversion

One may find below results of conversion for a true color ".jpeg" image. In AlgoLab Photo Vector conversion of raster images into vector ones includes two steps: preprocessing and vectorizing. The preprocessing consists of several consequent operations Shaping, Color Reduction and Cleaning that prepare an image to be vectorized. Preprocessing converts a blurred dirty image into one with clean solid colors and distinct boundaries of color shapes. These image processing operations may be useful beyond vectoring as well when clean solid colors and distinct shapes are required.

Consider a sample image "bug.jpg"

Figure 1. Original image "bug.jpg".

One may want to save this image and convert it to vector format to see the discussed below effects.

Shaping is an operation that provides conversion of blurred shapes into distinct ones. For instance a detail of the original image "bug.jpg" in Figure 1.a after Shaping looks like that shown in Figure 1.b.

Figure 1a. A detail of the original image "bug.jpg".

Figure 1b. The detail after Shaping.

Color Reduction reduces the number of used colors usually to the range 2 – 20 or to a number defined by user constructing a set of colors appropriate to an image and then makes fast color replacement. See Figure 1.c.

Cleaning provides elimination of small spots. See Figure 1.d.

After processing one gets clean image shown in Figure 2.

The operation Vectorizing gives outlines shown in Figure 3.

Figure 3. Outlines.

Outlines of a detail of the image are shown  in figure 3a. One can see that the outlines of adjacent color shapes coincide exactly over common boundaries. This provides exceptional cleanness and quality of vector image.

Figure 3a. 

Take a look at Figure 4 to to see the image obtained from the result vector image. It coincides with the preprocessed image and may differ by the scale only. No white spots or other defects.
