QUESTION
I am using Azure Face APi to detect faces in video stream, but for each detected face Azure returns a unique faceId( which is exactly what the documentation says).
The problem is, Let's say Mr.ABC appears in 20 video frames, 20 unique faceIds gets generated. I want something that Azure Face should return me a single faceId or a group of FaceIds generated particularly for Mr.ABC so that I can know that its the same person that stays in front of camera for x amount of time.
I have read the documentation of Azure Facegrouping and Azure FindSimilar, but didn't understand how can I make it work in case of live video stream.
The code I am using for detecting faces using Azure face is given below:
...ANSWER
Answered 2020-Nov-30 at 08:26There is no magic on Face API: you have to process it with 2 steps for each face found.
What I suggest is to use "Find similar":
- at the beginning, create a "FaceList"
- then process your video:
- Face detect on each frame
- For each face found, use find similar operation on the face list created. If there is no match (with a sufficient confidence), add the face to the facelist.
At the end, your facelist will contain all the different people found on the video.
For your realtime use-case, don't use "Identify" operation with PersonGroup / LargePersonGroup (the choice between those 2 depends on the size of the group), because you will be stuck by the need of training on the group. Example, you would be doing the following:
- Step 1, 1 time: generate the PersonGroup / LargePersonGroup for this execution
- Step 2, N times (for each image where you want to identify the face):
- Step 2a: face detect
- Step 2b: face "identify" on each detected face based on the PersonGroup / LargePersonGroup
- Step 2c: for each unidentified face, add it to the PersonGroup / LargePersonGroup.
Here the issue is the fact that after 2c, you have to train your group again. Even if it is not so long, it cannot be used in real time as it will be too long.

QUESTION
I have following problem: I let two functions write into my database. Before they get inserted into the database I check if a similar item exists:
...ANSWER
Answered 2019-Nov-20 at 22:34Even if the insertion order isn't relevant you still need to use await
in order to avoid race conditions.
Your full code queues up the following I/O operations:
- findSimilarOne
- insertListingOne (if findSimilarOne returns no match)
- findSimilarTwo
- insertListingTwo (if findSimilarTwo returns no match)
The only restrictions on the ordering of these operations is that #1 must occur before #2, and #3 must occur before #4.
The order that these are completing in is: #1, #3, #2, #4
Because both findSimilar
calls complete before either insertListing
completes, they both return no match.
You should use async
, like so:
QUESTION
I'm trying to loop through a concatenated list of two lists that is essentially a bag of words - example outputs yields [('brexit', 11), ('say', 11), ('uk', 7), ('eu', 6), ('deal', 5), ('may', 5), ..., ('brexit', 35), ('say', 28), , ('may', 5), ('uk', 1), ... ]
Having gathered all the text inputs from .txt files, I've removed the stop-words and using stemming to remove duplicated from tenses.
The next step I want to take is to loop through the list and find the differences in the number of appearances a given word - I would want 'brexit', 'say' and 'uk' to be flagged as significant words with either the two numbers of appearances or just the difference. My start of the code (partly python, partly pseudocode) is below.
...ANSWER
Answered 2019-Feb-11 at 14:21This would be an option. Not efficient, but the output is as desired. That is, if you want to delete word's with the same count (as shown in your code). If you want to keep the entries, just skip the biasDict.remove() part. If your just interested in the word's that occur twice with a different count, you could append the tuples to a new list instead of printing the difference. Afterwards return the new list.
QUESTION
I am building a celebrity matching facial recognition service. I have multiple pictures for each celebrity, and I want to match the user's query face to the closest celebrity. There are two ways to do this using Microsoft's Cognitive Services Face API:
- FaceList - FindSimilar to find the closest single face
- PersonGroup - Identify to find the closest person (making use of all faces)
Both can be used with 0 threshold (include all results), but which one would be more accurate? I am concerned whether multiple pictures in different light conditions, with different hairstyle, etc. used together will help or trip the detection accuracy. Thanks!
...ANSWER
Answered 2018-Jun-18 at 18:58It depends on what you want to do, if you want to return a collection of similar faces to the user based on their query, then go for Face - Find Similar, but if you just want to identify the people in a photo and return the possible identified person then Face - Identify would be the right choice.
Using multiple pictures in different light conditions, different hairstyles, and etc. for training will only increase the accuracy.

I'm not great at VBA, but all of a sudden, I started getting this error. Please let me know if you can find what the error is. I'm so stuck on this one. I did search everywhere and found lots of similar posts but the solution always seems to be very specific to the code. Any of you experts would be greatly appreciated.
Here's my code:
...ANSWER
Answered 2018-Feb-24 at 01:11A Run-time error '13': Type mismatch halfway through looping through a large set of values collected from the worksheet is almost always due to encountering a worksheet error code.
Are there any worksheet error codes (e.g. #N/A, #VALUE!, etc) in either Export!B2:B3500 or Topics!D767:D967 ?
I found one single #N/A cell. It was not there as an error but as a pasted value :-( It's working now!
You can quickly locate any worksheet errors in a long column of values (or even an entire worksheet) with these steps.
- Select entire column. If you want to look at the whole worksheet, just select any single cell.
2, Tap F5 then click Special.
- Choose Formulas and leave only Errors checked.
- Click OK.
Worksheet errors can also be found with one or both of the following.
