A Simple Way to Create Pointillistic Art from Natural Images

摘要

Back in the 19th century during the blooming age of impressionism a new branch of art has been introduced known as pointillism. This particular technique uses tiny dots as the brush strokes in order to create paintings. Both discrete up close as dots and continuous from distance as patterns are inherited in this form of art. We have taken inspiration from both the sector of art and the calculative form of digital image processing; by combining both of them we have presented a formula in order to create pointillism art. The most challenging part we have faced in the distribution of dots in other words pixels in the canvas and maintaining the subjective concept by regulation of the edges. At first color palette has been generated by finding out the most popular colors in the input image. Then some modification has been done for preserving better by RGB space to color space analysis. Then pixels are being converted as the pixel cluster according to stroke library. Finally, this clusters have been distributed in the canvas image for producing pointillistic image. We have also compared various form of distribution of pixel clusters and their effects as well as we have determined the necessary steps in order to give it the artistic effects. Most of all, art is a subjective sector; we have proposed one possible formula in a quest of creating towards the best.
