classifyGif() - server side

[ghnp5]

Hello,

Thank you very much for implementing NSFWJS, which works very well!

I use this as a Node.JS microservice app, doing Server-Side validation of photos uploaded to my website.

Works well for JPG images. The Node app retrieves an image from a URL, converts to buffer, runs tf.tensor3d(), then classify().

However, I am not sure how to classify GIF images, server side.
From looking at your code, it appears that the "gif" parameter must be a DOM img element.

Is it possible to classify GIF images server side?

I suppose I can manually go through every frame of the GIF and run classify(), but if this could be natively implemented in NSFWJS, that would be perfect!

Have a great day. Thank you.

I haven't run into the need to do this server-side just yet. I'd love to get a pull-request and merge the code so NSFWJS does this, would you be willing to solve it and send the code?

Unfortunately, I won't have the time to do a PR, but this is the way I got around it myself, using gifFrames:

		gifFrames({
			url: dataBuffer,
			frames: 'all',
			outputType: 'jpg',
			cumulative: true
		},
		async (err, frameData) => {
			if (err) {
				throw err;
			}
			frameData.forEach(function (frame) {
				const jpgStream = frame.getImage();
				... convert and classify, and add to an array
			});
		});
