How to check whether two images are similar or not? One image is captured by a cellphone and other is stored at cloud, without sending the whole image to cloud?I need to perform this at real-time.

You can

1) preprocess the 2 images to reduce the effect of the light conduction, rotation etc.

2) extract the feature for you image content, great feature is the most important part of image comparing.

3) compare the 2 feature sets, calculate the distance of the 2 feature vector. normalise the result

What about using pHash / perceptual Hash?
