I'm a 1st time Matlab user, with a small code with bwtraceboundary. This code once traced outline of a leaf image ( though without tracing the leaf stalk, which was a lighter shade)... before I changed the image size. then all I get out of this, for any image, is a blank.
Boundary of a set of points in 2-D or 3-D - MATLAB …

Use the boundary function to compute a boundary around the points, and find the volume of the resulting shape. [~, vol] = boundary (P); vol vol = 0.2962 Input Arguments collapse all x — x-coordinates of points column vector x-coordinates of points, specified as a column vector. Data Types: double y — y-coordinates of points column vector
Trace object in binary image - MATLAB bwtraceboundary
https://www.mathworks.com/help/images/ref/bwtraceboundary.html
B = bwtraceboundary (BW,P,fstep,conn) traces the boundary, where conn specifies the desired connectivity. example B = bwtraceboundary (BW,P,fstep,conn,m,dir) specifies m, the maximum number of boundary pixels to extract, and dir, the direction in which to trace the boundary. By default, bwtraceboundary identifies all the pixels on the boundary.
Boundary tracing using the Moore Neighbourhood - File …

2D boundary tracing using the Moore neighbourhood. USAGE ===== >> [listCONTOUR,listNORMALS] = TRACE_MooreNeighbourhood (data2D,pixelFIRST) takes the logical array <data2D> and traces the boundary of the region of 1s. The coordinates of the starting pixel are optionally defined by <pixelFIRST>. INPUT PARAMETERS ================

Determine the row and column coordinates of a pixel on the border of the object you want to trace. bwboundary uses this point as the starting location for the boundary tracing. dim = size (BW) dim = 1×2 246 300 col = round (dim (2)/2)-90; row = min (find (BW (:,col))) row = 27 Call bwtraceboundary to trace the boundary from the specified point.

I've tried to use both bwtraceboundary and bwboundaries to identify the edge outlines and then export this file with polylines, but am not having any luck. The original image is attached as is the code to convert the image to a binary edge-detected image. Any help is much appreciated! clear RGB=imread ('DJI_0022.jpg'); %inputs image

B = bwtraceboundary(BW,P,fstep) Nonzero pixels belong to an object and 0 pixels constitute the background. Pis a two-element vector specifying the row and column coordinates of the point on the object boundary where you want the tracing to begin. fstepis a string specifying the initial search direction for the next object pixel connected to P.
