I am trying to augment a text based on simple marker detection using Vuforia + Unity for Vuzix M400 device. What I want to achieve is the following - if the Camera detects both square and triangle, it should augment the text box "Select Box 1" and if the camera detects only a square, it should augment the text "Select box 2". Can somebody please guide/help on how could this be done? Thank you!
Ps.- This is for the first time I am using these tools so please spare me if the question is dumb or stupid. I am just trying to get some guidance and help from the community. Thanks.

I'm trying to do some image recognition using Open CV. I want to detect the position of a dark rectangle in a game called Diablo 2.
After detecting the position of the rectangle, I will extract the text of that rectangle using OCR.
I've prepared some examples using Photoshop of where are those rectangles located.
On the left you can see the game screenshot, on the right I've pointed out the dark rectangles using a red rectangle, that's the place I want to detect using OpenCV.
Which OpenCV method should I use to detect those dark rectangles?
I'm not sure if Open CV is capable of doing this kind of pattern recognition, would be great if anyone can point me out how to do it.
I'm trying to build a translator app which would be able to replace foreign text in the real-time, but after exploring possible approaches got a bit cornered.
Even though I was able to extract words images using Vision, I couldn't replace them in place in ARKit scene. Then I tried using ARReferenceImage and image tracking, but it needs to know the physical width of the target image which I can not guarantee, as the text could be on any surface from a book to a billboard.
Am I missing something? What would you guys suggest?
I Have an image for a homepage screen. The top part of the image when clicked should lead to the second tab, the left hand side of the image when clicked goes to the third tab and so on.
Basically geotagging an image , so that i can make areas of the image clickable leading to different tabs
I tried implementing using a map chart where i added an image layer, and added this image. Some solutions asked me to add a marker layer with x,y coordinates but I'm unsure on how to proceed on my image
Kindly help with any alternative solution
it sounds like you want an image map. "geo tagging" is when geographic info like latitude and longitude are added to an image.
your best bet is to use a text area with a table filled with image-type action controls. if you have Photoshop, you can use a technique called Image Slicing to prepare your images.
FYI, this is probably not a simple task, especially if you don't know much about HTML. you may want to consider a different navigation scheme.
if you update your question with more detail about the end result you are trying to achieve, maybe someone can share a more fitting solution. http://mywiki.wooledge.org/XyProblem
I have been doing some searching the last couple of days and I have been curious how to do this. I have a UIImagePickerController.
So I want to add a effect like black and white, sepia, etc. I am creating a custom UIImagePickerVController and I am curious. Can this be done with OpenGL ES? If so, how?
This is possible through the use of pixel shaders using OpenGL-ES 2.0. You could also write an Objective-c++ routine that gets all the pixels of your image into an array then applies a custom algorithm to modify the color of the image.

Here are some links that might help get you started.

I have an image with Gray Background and 'CUP' in center of it... I want to detect the boundaries of the cup in this image.. After detecting CUP I want to extract the CUP from the image using IMAGEMAGICK.. Note I have many images with different objects (like CUP) in the center and with different background color .. So I am looking for a solution which is applicable to all of them..
Plz comment..
Maybe you could use edge-detection algorithms to isolate the shape of your main object: http://en.wikipedia.org/wiki/Edge_detection
You could also look into the code for the EdgeImage effect in ImageMagick, to see how they do it...
