Select the background of your image then press backspace, or right-click and delete.

Right-click on a portion of the image, then choose Ungroup.

Select the image again, then click on Expand on the top menu.

Scroll through the options until you find one that retains the image quality you want.

You can undo your selection by using the shortcut Ctrl + z.

16 colors, for example, will vectorize an image into 16 separate colors. The higher the number of the color options you use, the more vector colors will be utilized.

Choose an option from the selection given to vectorize the image.

On the top menu, click the dropdown arrow to the right of the Image Trace button to bring up the menu.

Click on your selection icon on the left menu, and select the entire image.

Open the image that you want to vectorize.

If you’re using Adobe Illustrator as your image editing software of choice, converting the image to vector can be done by doing the following:

How to Convert Image to Vector in Illustrator The function that does the first part looks like this.If you want to know how to convert an image to vector for the different imaging platforms, read on. Then we'll turn it all into polynomial splines. First, we'll get points and tangents for every line segment from the pixels. Let's split our vectorization into two parts. It looks like we have enough parts to assemble an algorithm. And the ones that come from vertically oriented segments, will have dy > 0. Return pixel_in(pixels, i, pixels.length-1) Return pixel_in(pixels, pixels.length-1, j) The value is the linear sum of the four neighboring values. But this simply turns it back into a table.Ī little more advanced is the bilinear interpolation.

The simplest case would be the nearest neighbor interpolation, where for every point on an image, the value is the value from the nearest pixel's center. Let's say we only know the values in the centers of the pixels, and we have to guess the values between them somehow. Let's say our image is not a table of values. And for that, we have to make our image less cornery. Well, it's simple, but it's not what we wanted. Let's just agree on some threshold, and mark the contour of all the pixels that have the values exceeding this threshold. Technically, we can already turn it into vectors rather easily. Our image will be a simple gray-scale bitmap. Channels may be represented by integers or floating-point values. Apart from the colors of the visible specter they may contain ultra-violet and infra-red luminosity. Satellite images may have a lot of channels. It's not a color really since the values come from invisible X-ray radiation, but they are called gray values nevertheless. Medical images, such as obtained from computed tomography, are usually the tables of 12-bit or 16-bit integers.

Color pixels are the triplets of 8-bit integer values where each value represents an amount of red, green, and blue color. If it's a full-color RGB, then it's a table of color pixels. At the very least, it makes learning about all these things a little more compelling.Ī raster image is essentially a rectangular table of things. It shows how things like bilinear interpolation, gradient descent, and parametric splines work together to solve a real-world problem.

On the plus side, it illustrates the approach rather well. It's a basic vectorization technique which, in its original form, has little to none applications in the industry. The algorithm I'm going to show you has nothing to do with all these things. Or if you want to reissue an old game and you don't want to redraw all the artwork from scratch. Or if you want to scan some blueprint and turn it into a CAD model. It's especially useful when you want to turn a satellite photo into a map. Vectorization is when you take some minecraft-style raster image and make a crisp vector picture out of it.
