Hello. I have the image below that contains multiple cross cutting lines and I want to i) measure the length of each individual line and ii) the angle of each individual line. The lines are not perfectly linear, so task iii) would be to try and figure out a ...
To measure properties of objects in a 3-D volumetric image, consider using regionprops3 instead. Although regionprops can accept 3-D images, regionprops3 supports more statistics for 3-D images. When you call the regionprops function, you can omit the properties argument, in which case the func...
function RESULT=myrotate(IMAGE,ANGLE,METHOD) %MYROTATE Rotate image. % RESULT = myrotate(IMAGE, ANGLE, METHOD) rotates image IMAGE by ANGLE % degrees in a clockwise direction around its center point. To rotate % the image counterclockwise, specify a negative value for ANGLE. ...

In this case the logged roll angle and the position of the drone when the images were captured. Since the yaw, pitch and elevation of drone when the two images were captured were constant, they do not need to be captured for each frame. 2. Rotate the two images by their corresponding ...
I have a loop, in which I measure an angle in a series of images. If the angle is larger than the one before and the one after it should be omitted, otherwise it should be considered and appear in the results variable. Can anyone please help me and code...

Geometric camera calibration, also referred to ascamera resectioning, estimates the parameters of a lens and image sensor of an image or video camera. You can use these parameters to correct for lens distortion, measure the size of an object in world units, or determine the location of the ...
