cat-dataset VS functions-samples

Have a go at petswitch.com if you wish... I made the original Petswitch almost ten years ago, and it's had mild success since then, including CNET writing an article about it and it receiving the prestigious honour of 'most useless website' in week 41 of 2018, as determined by theuselesswebindex.com. Aside from the obvious question of why I even made this, it was getting pretty creaky – I originally built it with PHP and ImageMagick, with the facial features being manually selected via jQuery UI. So I decided to rebuild the whole thing with a full face-to-pet ML pipeline, on static hosting. To get the human face features, the app renders the upload to a temporary img element. This is a handy way to orient the image correctly via the browser, and saves having to deal with EXIF data. It's then resized, rendered to a canvas element, converted to a base64 string, then sent via fetch to Google's Cloud Vision API, which returns landmark coordinates of the face. I use these coordinates to correct any tilt on the face, mask the eyes and mouth via a mask image, then store each masked element as an additional canvas. Detecting pet faces was trickier. Google, Amazon and Microsoft all offer object detection APIs via transfer learning, and the approach is largely the same: you supply a series of images with bounding boxes around the objects you want to detect, either added via a web interface or uploaded via their API. You train a model online from these supplied images, then the service will return the estimated coordinates of any detected objects in an uploaded image. I found a dataset of both cats and dogs that had been labelled with landmarks on their faces, then wrote a script to convert the landmarks into bounding boxes around their eyes and nose, the dimensions based on a simple formula around the distance between the eyes in each image. All in all it's been trained on about 17,000 images of cats and dogs, and the accuracy seems to be pretty good. I was pleased to discover it actually works pretty well on other pets too. I've also added some friendly pets to the Petswitch family for those that don't have a pet on hand. I decided not to use a framework for this, it's written from scratch using a series of ES6 modules – although I did use Konva to handle the manual selection of facial features if the API can't detect a face. I used ParcelJS as my task runner, and my detection APIs are hosted on Firebase Cloud Functions. Let me know if you have any questions, although I can offer no good explanation for why I created this monstrosity...

I tried to make a reddit like app. I used both realtime-database and firestore as database. The billing of the two is different from each other. I used realtime-database for frequently updated data (like or upvote, downvote count for ex.) and firestore for more stable and large data (post, comment, community and user data..). While doing this, I only used database rules, I did not use Cloud functions. So, I suggest you use a hybrid database to minimize your bill as much as possible and you can do amazing things with database rules. Have a good works.

const functions = require("firebase-functions"); // // Create and deploy your first functions // // https://firebase.google.com/docs/functions/get-started // // exports.helloWorld = functions.https.onRequest((request, response) => { // functions.logger.info("Hello logs!", {structuredData: true}); // response.send("Hello from Firebase!"); // });

Try something along these lines…? https://github.com/firebase/functions-samples/tree/main/Node-1st-gen/quickstarts/email-users

Cloud Functions for Firebase - Pros: Aligns to my app which uses Firebase; Cons: have to use Typescript which I have no experience with

Cloud Functions run on Google's servers and are part of your project, so only you and your project collaborators can deploy that code.

That would be a Firebase Cloud Function. Check their latest list of YouTube tutorials, they'll guide you through creating an app with full Firebase features.

Cloud Functions for Firebase

Cloud Functions are a serverless solution that allows you to run backend code in response to HTTPS requests or even more ⚡ powerfully, in response to events triggered by other Firebase products.
