RAnEnExtra::pixelsSplitByY divide pixels according to cuts on along the y axis.
pixelsSplitByY( pixels, ycuts, xgrids.total, ygrids.total, start = 1, flag.sort = T )
| pixels | a vector of indices of pixels that will get divided |
|---|---|
| ycuts | a vector of integers specifing the y locations that will be cut. The range of the cut will be defined as [ycuts[i], ycuts[i+1]). |
| xgrids.total | total number of x. |
| ygrids.total | total number of y. |
| start | the counting start of pixels. |
| flag.sort | a bool specifing whether to sort the cut pixels or not |
a list of vectors with the separate pixels.
cut.pixels.along.y cuts the pixels into separate sets based on the cutting points specified in ycuts and the y coordinates of each pixel. The start counting index of pixels should be specified in the argument start. Note that ycuts should be counted from 1
