            My telegram userbot can forward a message in private but not in a supergroup
            Asked 2022-Mar-16 at 16:28

            I am writing a small project related to userbots in telegram. I had a problem when trying to forward a message from a supergroup to another user, but when I try to forward messages from a regular chat, everything is successful.

            Firstly, the error you get is clear. The Session of your userbot has not yet met the group and cannot identify it based on its ID. You will have to receive any kind of update from that entity first.
            See this FAQ entry: https://docs.pyrogram.org/faq/peer-id-invalid-error

            Secondly, the group you are trying to forward from may have forwards restricted in its group settings. Since you can forward via an official client, this is likely not the case.

            REST APIs and Unity3D: How could the server tell between a legitimate request sent by an official Unity build from some malicious cURL?
            Asked 2022-Feb-22 at 23:03

            --LONG VERSION--

            I made a super basic REST API to handle user account management (account creation, checking login credentials, etc.) that I will call from a Unity3D game, for which I plan to support mobile (mainly android).

            Players would upload drawings that they'd make with a drawing tool that exists inside of the Unity game. I made that tool for the sole purpose of preventing the possibility of someone either uploading a screenshot of a drawing that they didn't draw themselves, or someone uploading a selfie or a pornographic photo (for which I cannot allow the possibility to happen, since my game is primarily targeted to children), and those drawings can be publicly viewed by other players.

            --SHORT VERSION--

            To store an uploaded drawing I would use a simple $_GET['base64'], but in order to prevent disallowed images from coming in, how can I assure that the request is coming from an official android build and not, say, some cURL or a reverse-engineered Unity project?

            That's the whole question.

            In the case of a WebGL build I could just block any web request that is not coming from the domain that the WebGL build is in, but in the case of the android build however, as far as I know the server can't really tell a request sent by an official android build from some request sent by a cURL. And I'm pretty sure that someone, with a bit of effort, can figure out how my REST API works. I have no idea of how to effectively secure it.

            I'd like some suggestions, and if you think that my current approach is terrible (and it probably is) tell me how to improve on it or what to replace it with.

            If you are serious about preventing unauthorized clients from sending images to your server the easiest way is to forget about dealing with images entirely.

            Instead, I would have the clients and servers work with input data.

            1. Have the client record the inputs the user makes to create their drawing (or, if that is too much, something that approximates the outcome of their inputs, such as sequences of line segments, colors, stroke widths, sticker ids, whatever your drawing system uses). As they draw the image, replace what they just drew with your system's representation of it so they can be certain of its appearance before sending.

            2. Send, receive, and store the input data as needed

            3. When the appearance of the drawing is needed, play back the recording to reproduce the drawing.

            This is essentially how Jackbox does their drawing games, for instance.

            Using this method, someone could try to reproduce a vague depiction of a selfie or pornography with your API of input data BUT if you do things like limit the size of the data, limit the fidelity of the colors, limit the resolution of the start and end of the line segments, etc, the capacity for these things to be reproduced is further and further reduced until it becomes unfeasible.

            Poor selfie segmentation with Google ML Kit
            Asked 2022-Feb-02 at 01:04

            I am using Google ML Kit to do selfie segmentation (https://developers.google.com/ml-kit/vision/selfie-segmentation). However, the output am getting is exteremely poor -

            Initial image:

            Segmented image with overlay: Observe how the woman's hair is marked pink and the gym equipment and surrounds near her legs are marked non-pink. Even her hands are marked pink (meaning its a background).

            When this is overlayed on another image, to create a background removal effect, it looks terrible

            The segmentation mask returned by the ML Kit has confidence of 1.0 for all the above non-pink areas, meaning its absolutely certain that the areas non-pink are part of the person!!

            Am seeing this for several images, not just this one. Infact, the performance (confidence) is pretty poor for an image segmenter.

            Question is - is there a way to improve it, maybe by providing a different/better model? If I use something like the PixelLib, the segmentation is way better, albeit the performance of the library is not low latency, hence can't be run on the mobile.

            Any pointers/help regardig this would be really appreciated.

            It might be too optimistic to expect a lightweight real-time CPU-based selfie model to provide accurate segmentation results for a pretty complex and in a way tricky scene (pose, black color of the background and outfit).

            Official example highlights the fact complex environments will likely to be a problem.

            The only "simple" way of processing your scene is to use depth estimation. Just did a quick test with a pretty complex model:

            Results are too far from being usable (at least in a fully automated way). There are several other options:

            • Create a custom more sport-oriented model, trained on a proper dataset
            • Use a heavier model (modern phones are quite capable)
            • Use some reliable pose estimation in order to make sure a particular scene is selfie-compatible

            How to disable noise reduction with CameraX
            Asked 2021-Oct-26 at 10:47

            So I have an application that uses CameraX ImageCapture use case to take a selfie picture than then is passed to an AI algorithm to do some stuff with it.

            Now, I have an user with a Samsung Galaxy S21 who when taking pictures in one specific place with some specific light conditions is producing an image that doesn't work as expected with the AI algorithm. I have examined these images myself and noticed that the problem seems to be that ImageCapture applies strong noise reduction, so strong that even for the human eye it looks wrong, like if it was a painting instead of a photograph.

            I sent a modified version of such app to this user for trying which captures the image from the Analysis use case instead and the produced image does not have that problem, so it seems whatever it is, it's some post-processing done by the ImageCapture use case that's not done in the Analysis use case.

            Now, I don't seem to find a way to tweak this post-processing in CameraX, in fact I haven't even found how to do it with Camera2 neither. At first I thought it may be HDR, and I found there are some extensions to enable HDR, Night Mode and such in CameraX, but all these are disabled by default according to the documentation, and as far as you use the DEFAULT_FRONT_CAMERA none should be applied, and that's what I'm using.

            CameraSelector.DEFAULT_FRONT_CAMERA

            In any case it's clear that some heavy post-processing is being done to these images in the ImageCapture use case, so I'm wondering how could I disable these.

            BTW, I tried initialising the ImageCapture use case with CAPTURE_MODE_MINIMIZE_LATENCY in the hope that such flag would reduce the post-processing and hopefully remove noise reduction, but that didn't work.
