How to plot blurred points in Matplotlib

和自甴很熟 提交于 2019-12-05 03:27:15
As the question says, I'm looking for a way to plot blurred points using Matplotlib. I don't want to plot a set of points and then apply a filter to blurry the whole image. Instead of it, I would like to plot a set of points, each of them with an associated level of blur. Thank you in advance. Here's another work around. You can display an image at each location instead of a marker using a BboxImage . That way you can blur or manipulate the image any way you want. This tutorial has more about BboxImages . import matplotlib.pyplot as plt from scipy import ndimage from matplotlib.image import

Detecting how blurred an image is

允我心安 提交于 2019-12-04 19:23:23
I want to detect how blurred an image is, may be It can be called "blur extend". I found a useful paper for this: http://www.cs.cmu.edu/~htong/pdf/ICME04_tong.pdf I used OpenCV and implemented all steps from this paper, but the result is not same as result from this paper. Can someone give me any advise for detecting "blur extend"? ErmIg You can detect a blurring image with using next algorithm: Convert the image into gray format. Calculate the maximal absolute second derivative from the gray image (for every point): d[x,y] = max(abs(2*d[x,y] - d[x,y+1] -d[x,y-1]), abs(2*d[x,y] - d[x+1,y] -d[x

jQuery Blur Fires Before href

别来无恙 提交于 2019-12-04 19:23:11
I am trying to use an Ajax search\suggest box. I use jQuery to handle the textbox losing focus. However, when I click on a link in the suggestion list jQuery fires the blur event and the link is not followed. Here is the jQuery code: $(document).ready(function() { $('#lstxt').click(function() { this.value = ''; }); $('#lstxt').blur(function() { this.value = 'Database Search'; document.getElementById('ls').innerHTML=''; document.getElementById('ls').style.border='0px'; }); }); How do I get it to not fire .blur if a link is being clicked inside the suggestion list (id="ls_table")? var global

Smoothing Mat of float with mask

牧云@^-^@ 提交于 2019-12-04 14:40:07
Is there a way to apply a Gaussianblur or median smoothing filter to a mat of floating points while supplying a mask of pixels that should be ignored? could you please help me? ty. You can do this by: Zeroing out the regions outside the mask Smooth the image and the mask Divide each pixel in the smoothed image with the value of the smoothed mask The division in step 3 compensates for the black pixels introduced by masking. This works because the smoothed mask is darkened in the same way as the smoothed masked image. Yeah, so i figured it out. I had to define my own gaussian smoothing procedure

一个人想着一个人 提交于 2019-12-04 08:57:55
问题 If I add a DropShadowEffect to an parent element the text of the child elements are blurred. Why? <Grid> <Grid.Effect> <DropShadowEffect /> </Grid.Effect> <Grid.ColumnDefinitions> <ColumnDefinition /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <TextBlock Background="White">Test</TextBlock> </Grid> Update: with shadow without shadow 回答1: The reason why the text is blurred is because Effects cause the elements and all sub-elements to be rendered
