描述----------Description----------
This function images 2D the absolute values discrete wavelet transform coefficients arising from a imwd.object object.
此函数图像2D的绝对数值离散小波变换系数所产生的一个imwd.object对象。
用法----------Usage----------
## S3 method for class 'imwd':
plot(x, scaling = "by.level", co.type = "abs",
package = "R", plot.type = "mallat", arrangement = c(3, 3),
transform = FALSE, tfunction = sqrt, ...)
## S3 method for class 'imwdc':
plot(x, verbose=FALSE, ...)
参数----------Arguments----------
参数:x
The 2D imwd object you wish to depict
你想描绘的的2D imwd对象
参数:scaling
How coefficient scaling is performed. The options are by.level to scale the coefficients independently by level, anything else causes coefficients to be scaled globally
如何系数执行缩放。选项by.level独立缩放系数的水平,别的系数,在全球范围进行调整
参数:co.type
Can be "abs" for the absolute values of the coefficients to be plotted, can be "mabs" for the negative absolute values or "none" for none of this.
可以"abs"被绘制为系数的绝对值,可以"mabs"负的绝对值或"none",因为这都不。
参数:package
Can be "R" for the R package, or "S". The latter does less interesting things and results in a simpler plot
可以"R"的R包,或"S"。后者则有趣的事情,结果在一个简单的图
参数:plot.type
If this argument is "mallat" the coefficients at different scales and orientations are packed into one image and plotted, a format originating from Mallat's early papers on this. The other possibility is "cols" which plots each combination of scale and direction on a separate plot. This latter format is useful for examining coefficients, especially at the coarser scales.
如果这种说法是"mallat"在不同的尺度和方向的系数被打包成一个图像,并绘制,在此Mallat的早期论文的格式。另一种可能性是,"cols"绘制的每个组合的规模和方向,在一个单独的图。这后者的格式是非常有用的用于检查的系数,特别是在较粗的尺度。
参数:arrangement
If plot.type="cols" then this argument specifies how many rows and columns there are in the plot array.
如果plot.type="cols"那么这个参数指定的图阵列中有多少行和列。
参数:transform
If FALSE then the coefficients are plotted as they are (subject to the co.type argument above), if TRUE then the transform function supplied by tfunction is applied to the coefficients.
如果为FALSE,那么系数绘制的co.type的上述论点,因为他们是,如果为TRUE,则转换函数提供tfunction的系数。
参数:tfunction
If transform=TRUE then this function gets applied to transform the coefficients before plotting
如果transform=TRUE然后打印之前,此功能被应用到转换系数
参数:verbose
Print out informative messages
打印出的信息性消息
参数:...
Supply other arguments to the call to the image function. This is very useful to, e.g., can the colours, or other aspects of the image
供应其他参数调用image功能。这是非常有用的,例如,颜色,或其他方面的图像
Details
详细信息----------Details----------
Description says all
介绍说,所有的
值----------Value----------
If the package="S" argument is set then a matrix is returned containing the image that would have been plotted (and this only works if the plot.type="mallat" argument is set also.
如果package="S"参数设置,则返回包含矩阵的图像将被绘制(这只是工作,如果plot.type="mallat"参数设置也。
