Image Recognition based on color

April 5, 2019 - 12:23am #1

HI, 

I am trying to recognize similar objects based on the color. Vuforia doesn't support color detection as it converts the image into grayscale. 

I am going with different approach. 

1) Open Scene

2) Click on Button to take screenshot from the device.

3) Get this screenshot and compare it with the existing image in the device database. 

First two steps seem achievable but the third one is complicated. Is it possible to get the image from device database? And to compare the images, it is appropriate to use Texture2D.getPixel() ?

Any other way or solution to do color detection is highly appreciated. 

Thanks in advance, 

Meghaksh

Hello,

Vuforia Engine SDK 8.1 does not have APIs for submitting an image to the detector as it uses the live camera feed as input.

At this time I cannot think of a possibility to overcome this limitation, other than using our External Camera feature which, from your description, is likely not a fit.

Thanks,

Vuforia Engine Support
