How to apply canny edge detection in matlab?

Detect Edges in Images

Read the image into the workspace and display it. Apply the Sobel edge detector to the unfiltered input image. Then, apply the Canny edge detector to the unfiltered input image. BW1 = edge(I,'sobel'); BW2 = edge(I,'canny');

How to use imread in matlab?

A = imread( filename ) reads the image from the file specified by filename , inferring the format of the file from its contents. If filename is a multi-image file, then imread reads the first image in the file.

How do you find the rising edge of a signal in Matlab?

Transition out of state if the value of the input data signal rises above a threshold of 2.5. The rising edge is detected when the value of the expression signal-2.5 becomes zero or positive.
