使用Photoshop滤镜 给照片添加绚丽的方格背景

本文介绍用Photoshop滤镜来给照片添加绚丽色彩的格子背景。大致思路是：先把照片背景淡化,再用滤镜制作出一些颜色艳丽的斑点背景,然后利用格子滤镜转成格子效果,再用其它滤镜制作出边框线,颜色可以按需要随意调整。

多软件共用滤镜的安装诀窍

大家所熟悉的图像处理软件Photoshop,不但本身内置许多滤镜,而且有许多第三方厂家为其制作了大量的外挂滤镜(或称插件),如:KPT系列、EyeCandy系列等等。其实这些滤镜不仅适用于Photoshop的不同版本,而且也适用于Freehand、Illustrator等不同软件的不同版本。而我们安装这些滤镜的常用方法是直接把它们安装或拷贝(有些滤镜不用安装,只需拷贝到指定目录即可)到上述软件的Plug—ins目录下,这样的话,如果我们在同一系统(或不同系统)分

Boolean filters and positive implicative filters of residuated lattices

The aim of this paper is to introduce the notions of Boolean filters and positive implicative filters in residuated lattices and to investigate their properties. Several characterizations of Boolean filters and positive implicative filters are derived. The extension theorems of implicative filters and positive implicative filters are obtained. The relations among Boolean filters, implicative filters and positive implicative filters are investigated and it is proved that Boolean filters are equivalent to implicative filters, and that every Boolean filter is a positive implicative filter, but the converse may not be true. Furthermore, the conditions under which a positive implicative filter is a Boolean filter are established.     

Soft morphological filtering

Stack filters are widely used nonlinear filters based on threshold decomposition and positive Boolean functions. They have shown to form a very large class of filters which includes rank-order operations as well as standard morphological operations. The stack filter representation of an order statistic filter provides an efficient tool for the theoretical analysis of the filter.Soft morphological filters form a large subclass of stack filters. They were introduced to improve the behavior of standard morphological filters in noisy conditions. In this paper, different properties of soft morphological filters are analysed and illustrated. Their connection to stack filters is established, and that connection is used in the statistical analysis of soft morphological filters. Soft morphological filters are less sensitive to additive noise than standard morphological filters. The deterministic properties of soft morphological filters are also analysed and it is shown that soft morphological filters form a class of filters with many desirable properties. For example, they preserve well details of images.     

On filter theory of residuated lattices

The aim of this paper is to develop the filter theory of general residuated lattices. First, we extend some particular types of filters and fuzzy filters in BL-algebras and MTL-algebras naturally to general residuated lattices, and further enumerate some relative results obtained in BL-algebras or MTL-algebras, which still hold in general residuated lattices. Next, we introduce the concepts of regular filters and fuzzy regular filters to general residuated lattices, which are two new types of filters and fuzzy filters, and derive some of their characterizations. Finally, we discuss the relations between (fuzzy) regular filters and several other special (fuzzy) filters, and also characterize some special classes of residuated lattices by filters or fuzzy filters.     

Morphological Connected Filtering on Viscous Lattices

This paper deals with the notion of connectivity in viscous lattices. In particular, a new family of morphological connected filters, called connected viscous filters is proposed. Connected viscous filters are completely determined by two criteria: size parameter and connectivity. The connection of these filters is defined on viscous lattices in such a way that they verify several properties of the traditionally known filters by reconstruction. Moreover, reconstruction algorithms used to implement filters by reconstruction can also be employed to implement these new filters. We also show that connected viscous filters have a behavior similar to filters with reconstruction criteria. The interest of these new connected filters is illustrated with different examples.

The synthesis of complex spatial filters for coherent optical data processing

The key elements in coherent optical processors are the spatial filters. To realize the full potential of coherent processors much work should be devoted to the synthesis of and the production techniques for them. In this paper, some recent work on filters synthesis will be summarized, and the implications in optical computation, image processing (enhancement), image restoration (deblurring) and image detection examined. In addition, some advances on the production techniques for the spatial filters will be briefly reviewed. This would include the extension of Vander Lugt's filters to the multiply-exposed filters, the binary filters, the phase only filters, and the introduction of nonlinear filters.     

Asymptotic behavior of morphological filters

The connection between morphological and stack filters is used in the analysis of the statistical properties of morphological filters. Closed-form expressions for the output distributions of morphological filters are given, and their statistical symmetry properties are analyzed. Asytotically tight bounds on the expectations of two-dimensional morphological filters, and asymptotic formulas for the variances of one-dimensional morphological filters are derived. These results form the basis for analyzing general asymptotic properties of morphological filters.
