Authoring Images

I uploaded an image, but I cannot see the image on the "Collections" page. What could be wrong?

Most likely, you selected an image from the "Add Images" page, but you forgot to click the Start Upload button to complete the uploading process.

I uploaded many images to my collection. Where do I see the total count of images that I have uploaded?

The total count of images for each collection is displayed on the left panel of the “Collections” page. For more information, refer help for indexing


I tried to create a hotspot which was overlapping another previously created hotspot. But then I was not able to proceed further. Why?

When you create multiple hotspots, by default all hotspots are placed at the center. You need to re-position the hotspots such that they do not overlap each other. In your case, the hotspots were overlapping and hence you were not able to proceed further.

If the user tries to snap a region defined as hotspot, are the page hotspot links displayed or region hotspot links?

When the user snaps a region defined as a hotspot, then the region hotspot links are displayed. But if the snapped area covers all of the region hotspots defined for an image, then all of the region hotspot links plus the page hotspot links are displayed. Refer the table below for a better understanding of how the Ocutag sample code behaves.
Note: When an image or a portion of an image is clicked, the polygon of the clicked region is returned to the application. The information about the page hotspots, the co-ordinates of the region hotspots, and the relevant links for both the page and the region hotspots are also returned as meta-data for the image. It is up to the Developer to match up the polygon region with the page and region hotspot co-ordinates and decide the appropriate links to be displayed to the user.

Page Hotspot Links Total Number of Region Hotspots Number of Region Hotspots Covered in the Snapped Area Expected Recog Output




All links for 2 hotspots




All links for 3 hotspots + page hotspot links

Not Defined



All links for 2 hotspots

Can I add links to a region hotspot which is also common to the page hotspot?

Yes. You can have common links for both the page and region hotspots.

Handling Images

Can I index small images like logos and business cards?

Yes, you can index small images such as logos or business cards. If possible, upload a version of that image with a minimum resolution of 400 x 400 pixels.

Can I index black and white images?

Yes, you can index black and white images.

Suppose my app is trying to recognize multiple images captured in a single snap. What will happen?

If your app user captures two or more indexed images in a single snap, the Ocutag service will pass to the user the digital content associated with only one of those indexed images. The Ocutag service compares the photograph captured by the user (the query image) to images in a collection. As soon as one positive match is made, the Ocutag service returns to the mobile app the unique label associated with the image, and that label is used to perform a lookup, during a second server call, to retrieve the digital content (the metadata) associated with that image. Typically, the indexed image taking up the greatest area within the query image will be matched.

Can I download sample code for Android, iOS or Windows Phone for free?

Yes, you can download all our sample code for free.

How do I create and try out a Sample App?

First, download our Sample Code. Then, click Applications, and create a new application. This will provide you with "Application Credentials." Copy your "Developer Credentials" and the new "Application Credentials," a total of 4 keys, into the Sample Code, and then rebuild the application.

Will my Sample App work with the image I indexed?

Yes. In your Sample App, click Settings and choose the collection that contains your indexed image. Snapping the image should show you the links you added to it.

I downloaded the Android sample code, but the camera feature is not working properly on my device. What could be wrong?

The camera feature provided with the sample code is built using native camera codes. The camera module within the Android platform is highly dependent on the device and version of Android OS. The sample code has only been tested with the following devices:

1. LG P350 (Android 2.2 - Froyo)
2. Spice Mi310 (Android 2.2 - Froyo)
3. Samsung Galaxy S2 (Android 2.3.6 - Gingerbread)
4. Samsung Note (Android 4.0.4 - ICS)
5. Nexus 7 Acer Tablet (Android 4.2.1 - Jelly Bean)
6. Nexus 7 Samsung (Android 4.2.1 - Jelly Bean)

If you are trying the sample code on any device other than the ones mentioned above, you will have to integrate that specific device's camera module for the app to work correctly. It is your responsibility, as the developer, to integrate the camera feature so that it is compatible with your device.

Why do I see a blank graph for Recogs?

The Recogs graph shows how often users were snapping images with your app—how often your app was making image recognition requests—over a particular period of time. If you see a blank graph, this indicates that your app made no image recognition requests within that date range. To see data displayed in your Recog graph, try snapping an image with your mobile app, and then refreshing your graph. You should now see one image recognition request made on today's date. Or, if you're fairly certain that image recognition requests have already been made with your app, try adjusting the date range being displayed.

Why do I see a blank graph for Indexes?

The Indexes graph shows how many of your images, across collections, were indexed and on what days within a period of time. If you see a blank graph, this indicates that no images were indexed within that date range. To generate data to display, try indexing an image. Or, if you’re fairly certain that images have already been indexed, try adjusting the date range being displayed.

I want to know how many images I've uploaded and how many images I've indexed. Where can I see this information?

Go to the "Analytics" page. All of your "Account Statistics" including total numbers of uploaded and indexed images, will be shown on the right-hand side of that page.

Does the "Analytics" page show up-to-date information? How often does that data get updated?

Yes, the analytics page shows the latest data available.


I do not see any elaborate Business Pricing plans on your website. Can you give a brief about the pricing plans that you provide?

The plan suitable to you, depends a lot on your usage, like, the number of images to be indexed, the number of image recognitions you expect, etc. You can mail your queries to and we will work out a plan tailored to suit your needs.

What is a free plan?

When a developer registers with Ocutag, the developer is by default placed under free plan. A free plan is where the number of enabled images in all your collections should not be more than 10 at any one time, and the number of recogs should not be more than 100 per day.

How long can I use the free plan?

You can use the free plan as long as you restrict the number of enabled images in all your collections to 10 at any one time, and the number of recogs to 100 per day.

How do I subscribe to a paid plan?

You need to contact support or mail your queries to for the pricing plans customized to your needs.

On what basis is the bill calculated?

Your bill calculation is based on your peak value of images enabled and the number of recognition requests, made for one month.

What do you mean by peak value?

The maximum number of images enabled in one month is called the peak value for that month. For example, you enabled 50 images (peak value) for January. Later you disabled 10 images, which makes the number of images enabled to 40. Even though at the end of January you have enabled only 40 images, but your peak value 50, is taken into account for bill calculation.

When is the due date to pay the bill for the current month usage?

The due date for the current month usage is the last day of the next month. For example, the due date for January 2014 bill would be February 28 2014.

What will happen if I don't pay the bill even after the due date is over?

If you fail to pay even after the due date is over, you will be blocked from the start of the next billing cycle. For example, the due date for Jan 2014 bill is Feb 28 2014. If you fail to pay the bill by Feb 28, you will be blocked from March 1, which is the start of the next billing cycle.

Where can I view my previous months’ bill?

You can view your previous months’ bill on the Billing page > Previous Bills section. Select a month from the drop-down list and click Fetch Bill. Alternatively, you can also click the available monthly bill links

What does the Bill usage trend represent on the Billing page?

The Bill usage trend is a plotted graph with your monthly bill amounts against each month

Is it safe to provide my credit card information?

Yes. It is safe to provide your credit card information, as we use industry-standard SSL technology with an encryption key length of 128 bits. Your information is secure and cannot be intercepted by third parties.

What should I do if my Ocutag Account is de-activated after failing to pay the bill amount?

You must pay your entire outstanding bill amount to start using the Ocutag services again.
