    • Systems, methods and computer program products are disclosed for resampling a digital image. According to an implementation, a source image can be presharpened and upsampled to a first upsampled image having a specified image size and a first level of presharpening. The source image is also presharpened and upsampled to a second upsampled image having the specified image size and second level of presharpening that is less than the first level of presharpening. The first and second upsampled images are deblurred. A binary edge mask image is generated from the deblurred, upsampled images. The binary edge mask image is dilated and blurred to generate a deep mask image. The first and second, deblurred upsampled images are blended together using the deep mask image.
    • 公开了用于重新采样数字图像的系统,方法和计算机程序产品。 根据实施方案,源图像可以被预先磨合并上采样到具有指定图像尺寸和第一级预锐度的第一上采样图像。 源图像也被预先磨合并且被上采样到具有指定图像尺寸的第二上采样图像和小于预锐化的第一水平的预锐化的第二水平。 第一次和第二次上采样图像被去毛刺。 从去除模糊的上采样图像生成二进制边缘掩模图像。 二进制边缘掩模图像被扩张和模糊以产生深度掩模图像。 第一个和第二个去除模糊的上采样图像使用深度掩模图像混合在一起。

    • A method to accurately create a multi-image mark-making tool so as to simulate digitally the rendering of a printed articulation, stroke, or mark of a donor natural medium used in graphic arts, such paints, pencils, erasers, or other implements. Using a computer or other hardware the method provides a digital representation of multiple-image elements to simulate an implement tip, receptor grain and variable grain penetration, and smooth and continuous brush stroke without visible artifacts. The method allows for isolating a plurality of image elements, masking the image elements, creating a grid of image elements to function as an index of an array of the image elements, creating a file of such image elements for the purpose of accurately simulating brushes and other donor-receptor articulations common to natural media, and for rendering a brush stroke in multiple-images to accurately simulate digitally paint brushes and other implements.
    • 一种准确地创建多图像标记制作工具的方法,以便对图形艺术(例如油漆,铅笔,橡皮擦或其他工具)中使用的供体天然培养基的印刷的关节,中风或标记进行数字模拟。 使用计算机或其他硬件,该方法提供多图像元素的数字表示以模拟器具尖端,受体颗粒和可变晶粒穿透以及平滑且连续的笔触笔划,而无可见的伪像。 该方法允许隔离多个图像元素,掩蔽图像元素,创建图像元素的网格以用作图像元素的阵列的索引,为了精确地模拟画笔而创建这样的图像元素的文件,并且 对于天然介质常见的其他供体 - 受体关节,以及用于在多个图像中渲染画笔冲程以精确地模拟数字绘画刷和其它工具。
