I am new to iOS projects. In my current project, I have to process an image which contains LED object. I want to extract the LED object status (on/off) from that image in iOS. Is there any open source library to process the image for my scenario. Please help me.
Thanks in advance.
I think there is an opencv port for ios.

You could use OpenCV. But honestly for what you want to do, doing it yourself would be way easier.

I am making a music player app. It is able to read the files but I am not sure how to extract the metadata. I want to be able to fetch the song length and the album image mainly. Though the album image might be a problem I am also happy with other data like the song duration and album name and other stuff.
I would be really helpful if someone could provide me a way. I referred to id3 package but there isnt much written as to how to handle the output. A proper code example would be really helpful. I am a complete beginner in dart.
THANKS WORLD.
Similar question Local Audio files metadata in flutter.
Right now you can use flute_music_player package for achieving the said task but it is only available in Android as of now. So my best guess will be for you to write Platform channel for iOS
You can try this package and check if it still works. It's not updated recently media_metadata_plugin
I am creating an iPhone application for image morphing using OpenCV 2.4.3. I am able to do the morphing but some noise/distortion is also getting introduced. I am not able to identify where the source of this noise or how to remove it. Please help me out if someone has faced any similar issue or has any experience in image processing. I have attached a sample input/output for reference. Thanks in advance :)
What I actually need is something like this:
I want to build a similar app as fatbooth and want some ideas on how to do this. I googled for Image morphing in iPhone but didn't find anything. Should I use some server side language to morph Image?
Any help would be much appreciated!
Thanks

The only language you can really use is C# or c++. the maths is very complicated although I am sure you can get a book or two that cover image manipulation.
I don't know if there is an open source morphing framework, but that is your best option - it doesn't have to be specific to the iPhone, but the integration will be hard.
I don't know what you mean about server side, unless there is a server you know of that does it and you want a wrapper around it
For starters, take a look at displacement mapping: http://www.imagemagick.org/Usage/mapping/
Basically, you use grayscale images to bloat/shrink/squeeze/etc parts of a person's face. I made an app called FaceCraze which had to implement a poor man's FatBooth as part of the face transformation, and I used grayscale images very similar to the examples in http://www.imagemagick.org/Usage/mapping/#spherical
edit: You can use the ImageMagick library in your iOS apps too: Link
I am developing a application where i want to load the image on flickr.I have seen the Snap and Run project where i tried to share the image using my API key but cannot do it.
its giving response as invalid callback url. Can anyone help me with this as I am not able to do this,,
Thanks in advance,
Try the ObjectiveFlickr project: http://github.com/lukhnos/objectiveflickr
You'll need to give us more detail if you want a better answer.
i wanna ask that , is there any api to recognize image?
i need read data from image...can i read numbers which is printed on image..
It seems as though there is no built in function for OCR and this would have to be a custom aspect not found in foundation.
Good luck!
You can always download an open-sourced, external library (package) to do the OCR. GOCR is one example.
There are many OCR libraries available for reading text from an image. You can check my answer Mobile OCR Engine for iPhone app
and for reading numbers only check my answer How to read numbers only in an image
Hope it helps you.
