Scaling An R Image

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-23 20:15:07
问题 I'd like to scale an image in R for further analysis rather than for immediate plotting. EBImage's resize() would be ideal for this if I could use EBImage, but I need to avoid it so I have to find an alternative. I haven't had any luck searching. I could implement bilinear filtering by hand, but before I do that I'd like to confirm that there aren't any alternatives. 回答1: Nearest neighbour resizing is the most common and simplest to implement. Assuming your image is one layer/channel, and

Reversing scaled values in LibSVM

问题 I am using Support Vector Regression for forecasting in LibSVM. I work it all. However there's one question that sticks in my head. For LibSVM, I firstly scale my training and testing set in the same range and then select the optimal parameters. After I run svm-train and svm-predict, I get the forecasted values for testing set in a scaled format. I am using Excel and reverse the scaling and calculate Mean Absolute Percentage Error (MAPE). I a pretty sure that scaling in LibSVM works like that

Scale WindowsForm

问题 Basically, I want everything (Controls etc) to scale with the WindowsForm when resizing it by dragging, so that the user can determine the size of the UI himself. The picture is not perfect, but I hope it explains it: The easiest way to do this would be to use a (Flow/Table)LayoutPanel and the appropriate Anchor/Drop properties, but I feel like that restricts my design, which currently looks like this: My idea was to scale all the components when Resize() is called: foreach(Control c in

iOS Aspect Fill Image Resizing with Content Aligned to Left/Top Edge

由 徘徊边缘 提交于 2019-12-23 16:06:56
问题 I am developing a universal app for iOS-7. this particular question is specific to iPad only. I want to place an image as background of root view of a View Controller i.e. the image should fill the whole screen. The 1x image has size:768x1024. This works for Portrait orientations as non-retina resolution of iPad is also 768x1024 in portrait. In Landscape however the image does not fit. I have tried using ScaleToFit but since aspect ratio of image is not preserved I can not use ScaleToFit

how do I properly position & scale these elements in CSS?

问题 I've been able to properly position & scale a few elements in my webpage using html & css, however due to the rules of positioning, I've gotten stuck on how to continue this action with two more elements. The chevron icon in the picture must be below the last paragraph entitled "scroll down", & I also want it to scale with the screen size as I have been successfully able to do with the other text/elements as you can see: here is the html: <!DOCTYPE html> <html> <head> <title>myWebpage</title>

How does excel+powerpoint decide to rescale ranges pasted as images?

问题 I've noticed that when you copy a range in excel (copy as a picture - as shown on screen) and paste it into PowerPoint, the resulting image is not scaled 100% to the original image (right click on image, go to format settings and go to size to see scale info). In addition, this scaling differs on different computers (might be related to graphics card). If you have different versions of Office the scaling also differs per computer (i.e. in Office 03, scaling is 100% of original, in Office 07,

Two layouts for two aspect ratios (4:3 and 16:9) - changing automatically

由 隐身守侯 提交于 2019-12-23 11:44:11
问题 Following the Microsoft scale guidelines there is a part where it says: When designing a fixed layout, start by designing your layout for the baseline resolutions: 1024x768 and 1366x768. Regarding this I have the following question: Is it possible to define two fixed layouts for two aspect ratios (both to be used with the ViewBox to scale to every resolution in that aspect ratio) so they can change automatically depending on the screen's aspect ratio? And maybe change between the fill mode
