摘要： A method for enhancing an input image to produce an enhanced output image is provided. The method includes constructing a photographic-mask intermediate image without low-contrast details and a temporary-image intermediate image with enhanced mid-contrast details, retained high-contrast details, and reduced low-contrast details, and employing values for the photographic-mask intermediate image and temporary-image intermediate image to produce the enhanced output image that is globally and locally contrast-enhanced, sharpened, and denoised.

摘要： Various embodiments of the present invention are directed to methods and systems for image processing that are unified in nature, carrying out many image-enhancement tasks together in a unified approach, rather than sequentially executing separately implemented, discrete image-enhancement tasks. In addition, the methods and systems of the present invention can apply image-enhancement to local, spatial regions of an image, rather than relying on global application of enhancement techniques that result in production of artifacts and distortions. In certain embodiments of the present invention, various different types of intermediate images are produced at each of a number of different scales from a received, input image. From these intermediate images, a photographic mask and temporary image are obtained, and the photographic mask and temporary image are then employed, along with a look-up table or function that receives values from the photographic mask and temporary image, to compute an enhanced, output image. In a described embodiment of the present invention, the intermediate images include low-pass, band-pass, photographic-mask, and temporary-image intermediate images computed at each of a number of different scales.
摘要翻译：本发明的各种实施例涉及用于图像处理的方法和系统，这些方法和系统本质上是统一的，以统一的方式一起执行许多图像增强任务，而不是顺序执行单独实现的离散图像增强任务。此外，本发明的方法和系统可以将图像增强应用于图像的局部，空间区域，而不是依赖于导致产生伪像和失真的增强技术的全局应用。在本发明的某些实施例中，在从接收的输入图像的多个不同尺度的每一个处产生各种不同类型的中间图像。从这些中间图像，获得摄影掩模和临时图像，然后使用摄影掩模和临时图像，以及从摄影掩模和临时图像接收值的查找表或功能，以计算增强的，输出图像。在本发明的一个描述的实施例中，中间图像包括在多个不同尺度的每一个处计算的低通，带通，照相掩模和临时图像中间图像。

摘要： An image is processed in a device-independent color space by applying a modification function to one or more dimensions of that color space. The image is then converted into a target device-dependent color space. In order to minimize unwanted changes of color arising from the modification function taking image color values out of gamut when converted to the target device-dependent color space, the modification function is scaled to limit modified image values to within modification limits that are determined, for each image pixel or group of pixels, in dependence on the target device-dependent color space gamut boundary in the device-independent color space.

摘要： A method and apparatus as provided for determining, for an ink to be deposited on a substrate by a halftone inkjet printing process, a nominal coverage value (the ‘ink restriction value’), that corresponds to an amount of ink sufficient to fully cover the area of the substrate to be printed. This determination is effected by measuring the reflectance of the printed substrate for a range of nominal coverage values, and then using an automatic processing arrangement to determine, from the change of measured reflectance with nominal coverage value, the nominal coverage value at which continuous tone behavior commences.

摘要： Provided are systems, methods and techniques that estimate the noise level in a signal, such as an image, by ordering windows in the signal based on calculated measures of the variability within each window (i.e., ordering from lowest to highest or, alternatively, from highest to lowest). That order information is then used together with the calculated measures of variability to form an estimate of the noise level. Typically, the techniques of the present invention generate this estimate based on the windows having the lowest or the second-lowest or the several lowest, depending upon the nature of the image, measures of variability.
