opencv - Difference between Fundamental, Essential and Homography matrices -


i have 2 images taken different positions. 2nd camera located right, , backward respect 1st camera. so think there perspective transformation between 2 views , not affine transform since cameras @ relatively different depths (am right ??) have few corresponding points between 2 images. think of using these corresponding points determine transformation of each pixel 1st 2nd image.

i confused functions findfundamentalmat , findhomography.... both return 3x3 matrix, difference between 2 ??

is there condition required/prerequisite use them (when use them)??

which 1 use transform points 1st image 2nd image?? in 3x3 matrices functions return, include rotation , translation between 2 image frames??

from wikipedia, came know fundamental matrix relation between corresponding image points. in answer here, said essential matrix e required corresponding points... not have internal camera matrix calculate e.....i have 2 images.

how should proceed determine corresponding point? awaiting suggestions.. thank you

there 2 cases transformation between 2 views projective transformation (ie homography): either scene planar or 2 views generated camera rotating around center.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
