问题 I have a program where I get one image as input and I have to compare it with ~640 known images to see which one is the most similar. To do this I was thinking of using OpenCV's match template, as it seems very fast and effective in doing what I want to do. I noticed that matching two images, both 400x240 px, 1000 times is much slower than matching a 400x240 px image in a 1400x240 px, despite both of them being 1000 matches. My idea was to combine the 640 images in one big image containing

Or is it possible to archive the same result without setting the height? Also,

问题 I'm using Gaussian Process model for prediction, and I'm now at the point where I need to use Grid file based on the coordinates I have in my data but I don't have one and I don't know how to create it. I followed the post on this link , but it shows the grid on Pennsylvania not Chicago where my data coordinates located! So I'm confused which will be the ideal way to create grid file including the other columns in the data. station <- data.frame(lat = c(41.997946, 41.960669, 41.960669, 41

use npc units in annotate()

让人想犯罪 __ 提交于 2021-01-19 06:41:07
问题 I have a ggplot object. I would like to add some text with annotate() , and I would like to specify the coordinates of the text in npc units. Is this possible? This minimal example demonstrates how text is ordinarily positioned with annotate() : library(ggplot2) p <- ggplot(mtcars, aes(mpg, wt)) + geom_point() p + annotate("text", x = 30, y = 4.5, label = "hello") I would like to achieve the same effect, but instead of specifying x and y in native coordinates, I would like to specify them
