(一)“打马赛克”本来指用特定颜色的小拼花,或瓷片或建筑材料等,拼凑在墙砌缝中拼花装点房屋外观,形成图案。后来也指计算机图像处理领域中的图像处理方法,把一张完整图片处理成一个微型的花瓣,用来保护图片知识产权的一种技术。
(二)打马赛克技术处理的原则是,给特定图像赋予一定的价值,从而把它转变成艺术化的风格,使原来的意义发生变化,生成不同的美感。通常,采用的最广泛的打马赛克处理技术是在原图像上生成许多小的正方形或长方形块,并用这些小块对原来的图片填充相同或相似颜色,把图片中细节和完整形象都覆盖隐藏。上手难度中等,适合初级图片处理者。
(三)当“打马赛克”被应用到图片处理中时,它可以用来把图片中的某个区域覆盖起来,以防止这些区域的细节被复制,复印,以及别人使用。此外,“打马赛克”技术可以用来处理非授权的图片,比如违禁图片,进行信息披露,同时又保护照片的拍摄方的类似权利,这是最常见的应用。
(四)使用“打马赛克”技术的时候,可以使用不同大小和形状的花色,来实现需要类型的效果,比如,用立方体马赛克把细节错乱到整体图案中,使得整体图案发生变化,从而达到艺术化的效果。此外,使用不同的花色组合,可以制造出特定的图案,具有较高的图片处理水平,可以帮助图片的创作者达到更高的审美境界。
(五)最后,通过打马赛克技术处理的图片,还可以用于艺术、商业等多种用途,比如展示活动,应用到媒体,用于商业、网络等。然而,无论是使用“打马赛克”还是其他图片处理软件,都应遵守版权法律。图片发布者和图片使用者都应该知晓并遵守版权保护法,以确保图像权利的保护和合法使用。
1. Mosaic: A mosaic is a piece of art that is created by arranging small, colorful pieces of material. This could be broken pieces of tile, glass, stone or even natural materials like shells, feathers or wood. Mosaics date back to ancient times, and have been found on walls, floors and pavements around the world.
2. Pixelation: Pixelation is the process of covering an image with small, square blocks of color, usually to hide the identity of a person or another object. Pixelation is achieved by reducing the image to the lowest resolution it can be without losing clarity, then changing the pixels to a different color.
3. Pixel Art: Pixel art is a form of digital art that is created by using small, colored dots, or pixels, to create an image. Pixel art is often used in video games and was originally created for the 8-bit consoles of the 1980s and 1990s. It has since grown in popularity and is now being used to create professional designs.
4. Blurring: Blurring is a technique used to obscure an object or background in an image. This can be done digitally, with software or a brush tool, or optically, using a camera or lens. Blurring can be used to give a sense of depth to an image, or to remove details that are not essential.
5. Block Mosaic: A block mosaic is a type of mosaic made up of rectangular pieces that are arranged in a grid pattern. Block mosaic is commonly used in modern murals and art installations, as the grid pattern allows for a much greater range of designs. It can also be used to create photographic effects like pixelation.
