Fix Typo In EdgeDetect Module

[harshkhandeparkar]

Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!

We know that the process of creating a pull request is the biggest barrier for new contributors. This issue is for you 💝

If you have contributed before, consider leaving this one for someone new, and looking through our general help wanted issues. Thanks!

🤔 What you will need to know.

Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.

To Do: Fix a typo in EdgeDetect module source code which doesn't affect functionality but is better to be fixed.

📋 Step by Step

• 🙋 Claim this issue: Comment below. If someone else has claimed it, ask if they've opened a pull request already and if they're stuck -- maybe you can help them solve a problem or move it along!

• 📝 Update the file Module.js in the image-sequencer repository (press the little pen Icon) and edit the line as shown below.

Change options.hystereis to options.hysteresis
Here

image-sequencer/src/modules/EdgeDetect/Module.js

Line 10 in c645732

options.hystereis = options.hysteresis || defaults.hysteresis;

And here

image-sequencer/src/modules/EdgeDetect/Module.js

Line 30 in c645732

pixels = require('./EdgeUtils')(pixels, options.highThresholdRatio, options.lowThresholdRatio, options.hystereis);

See this page for some help in taking your first steps!

Below is a "diff" showing in red (and a -) which lines to remove, and in green (and a +) which lines to add:

On line 10

-  options.hystereis = options.hysteresis || defaults.hysteresis;
+  options.hysteresis = options.hysteresis || defaults.hysteresis;

And on line 30

-      pixels = require('./EdgeUtils')(pixels, options.highThresholdRatio, options.lowThresholdRatio, options.hystereis);
+      pixels = require('./EdgeUtils')(pixels, options.highThresholdRatio, options.lowThresholdRatio, options.hysteresis);
