Hello, For those interested, I have developped a (simple) NHW Neatness Metrics to measure neatness between 2 images: the studied one and the reference one. The results are the significance of the neatness on the whole image and the average neatness amount. This work is experimental and could be incomplete for this first version! But it shows that the NHW Project has...

Hello all, Finally find some time to get back to the NHW Project.I was thinking about making a technology demo, and I wanted to highlight the uniqueness of the NHW codec that is neatness/sharpness preserving or enhancement.With my eyes, I can see that the NHW codec has more neatness/sharpness than the other codecs (x265, x264, WebP, Rududu, JPEG,...), but for a demo there must be objective metrics, and this is where things complicates.... I have tried to make quickly a neatness/sh...

Hello, For those interested, I have added a -l8 "very high compression" setting to the NHW Project. I have added an experimental processing to remove details and preserve neatness.I have also now a fast estimation of entropy of wavelet coefficients and I use it accordingly to the image complexity but it is a very first version... With these new processings, the entropy coding schemes are less efficient, and so we could save for -l8 setting nearly 2KB per compressed .nhw file...

I would like to make a new vector with values taken from two existing vectors conditional upon a third. At present I am doing this with a for loop but wonder if there is not a neater way, given some of the very neat things R can do. a<-rep(c("A","B"),50) b<-rep(1,100) c<-rep(2,100) a is thus "A" "B" "A" "B" "A"

Hello, Just a word to let you know that I have improved -l7 high compression quality setting, thanks to a new processing and I have also corrected an error in the residual coding.Now it has more neatness/definition.Files size is also a little smaller (and please keep in mind that the entropy coding schemes are not optimal for now, so we can save 1.5Ko-2Ko per .nhw file). Actually I find -l7 quality setting now quite competitive with x265 (HEVC) because we clearly see that the NHW codec has more ne...

Hello, Just a quick message, I have improved the NHW Neatness Metrics.It is now better and more representative of neatness of image.

I have done a cluster analysis doing: 1-clusNorth <-hclust(dist(Artorious)^2, method="ward") 2-clusNorth$labels <-Artorious$Name ## to show the case names and not numbers 3-dend1 <- as.dendrogram(clusNorth) 4-plot(dend1) My Dendrogram is now showing the names of my cases in the dataframe on the x axis 1 OMNICELL INC COM 2 GETTY IMAGES INC

Hi Group, I often need to print out data frames with results of analysis into a neat little image to copy and paste into documents. I need apply formatting like bold, currency signs, number formats, header shading etc. I currently output the data into csv and format using good old excel. Any suggestions if there are packages to help with such activities (to some level of basic functionality). I

Has anyone implemented "hot seating" in any neat way? This where people can log in to any phone in the company and have their calls/voicemail come to that particular handset.....

Hi, I wish to NEATLY store, and later display one table per file (similar to capabilities of write.table()). BUT BY NEATLY I MEAN: 1. Column Headings right aligned with data values. 2. Decimal points line-up per column. 3. Data values padded trailing zeros per column (if not integers). 4. "Tricky" formats such as certain characters/dates possibly chosen by the user? bla bla bla I do

You're missing a comma in the subscript. The comma tells it that your test is for the appropriate rows. You want: finest[finest[,1] > 10^3,] Hope this helps, Matt Wiener -----Original Message----- From: Edmond Ng [mailto:Edmond.Ng at lshtm.ac.uk] Sent: Monday, March 24, 2003 2:40 PM To: r-help at stat.math.ethz.ch Subject: [R] how to show a section of a matrix neatly (or row by row)

Hi all, I am looking for recommendations/pointers about best report generator you think that are currently available? i.e. the package that can help turn console output into nice-looking neat report to send to bosses? thanks a lot! [[alternative HTML version deleted]]

Is there any neat way to add a curve (frequency function or the like) to a histogram or other plots? I haven't found one yet... Robert

...rent modes + residual coding scheme, but I just apply residual coding on the first order wavelet "image" (for example for a 512x512 image, I just code the errors on the 256x256 wavelet "high-resolution" part), hence the lack of precision.I try to compensate it with a little more neatness of the wavelet 5/3 filterbank, but that's right that precision seems visually more important. Any opinion on this approach or on the codec in general is very welcome. Many thanks again, Raphael -------------- next part -------------- An HTML attachment was scrubbed...

...logspot.com/ I am still trying to improve my codec, and so any comments and advice are very welcome.I had few, but great discussions with Monty Montgomery and he also encouraged me to post and present my work on the channel. Very quickly, the main features would be a fast decoder and maybe a good neatness.You can find few results on the demo page.You can also download the win32 binaries to test it. -I am planning to give the source code and algorithm detail rather quickly, but currently the codec is absolutely not finalized, I am changing algorithm every month currently(...), would also have to adap...

Hi all, I want to show the rows of a matrix (100x3) of which some of its elements satisfy a certain condition. In particular, how can I display the 2 rows of my matrix one after the other and not all all elements of column 1 first, then column 2 and so on. See the following. > finest[finest[,1] > 10^3] [1] 4.960632e+13 3.612619e+04 7.668204e+12 1.001911e+04 8.886153e-01 [6]
