To develop this project, we need three primary packages: jimp, jsdom, and node-canvas.
The jimp package allows us to load images for use with OpenCV.js. The jsdom and node-canvas packages provide the necessary environment to enable cv.imread() and cv.imshow() functions respectively.
Keep in mind, while installing these packages, you may encounter some errors. To troubleshoot and successfully install these packages, it's recommended to review the installation documentation for each one.
Please note that there are specific additional dependencies required for node-canvas.
