annt¶
Description¶
Various tools have been developed so far for object detection tasks. However, there are no standard in annotation tools and formats and developers still write their own json or xml parser of annotation files. annt is an annotation tool that operates in the form of cloud services such as dropbox. annt provides not only simple and comfortable annotation exprience, but also powerful library for loading annotated images.
This is a documentation for python library which read images annotated with annt. you can load annotated images in a simple way and focus on the essential AI development. Also, this library has a basic build-in preprocessing functions. So you can save time to write extra code.
Examples¶
Example 1. Load annotated images¶
import annt
# annotations is list of annotation data
annotations = annt.load('./Dropbox/app/project_name')
# Display ths information of each annotation file.
for a in annotations:
image = a.image # opencv2 image array
boxes = a.boxes # list of bounding boxes
height, width, colors = image.shape # you can
for box in boxes:
# Tag information (str)
print(f'~ tag name : box.tag ~')
# You can get coordination information of the box by two methods,
# Left Top Style and Edge Style.
# Coordination information based on left top of the box. (Left-Top Style)
print(f'x : {box.x}')
print(f'y : {box.y}')
print(f'w : {box.w}')
print(f'h : {box.h}')
# Coordination information based on the distance from each edge of the image. (Edge Style)
print(f'left : {box.left}')
print(f'right : {box.right}')
print(f'top : {box.top}')
print(f'bottom : {box.bottom}')
# If you change these coordination properties, all of them will recomputed.
box.w = 300 # This operation will also change box.right property.
Example 2. Data augumentation¶
import annt
import random
# annotations is list of annotation data
annotations = annt.load('./Dropbox/App/annt/test')
sample_n = 10 # Number of samples from one image
# Display ths information of each annotation file.
augumented = []
for raw_a in annotations:
for i in range(sample_n):
# Rotate image
rot_deg = random.choice([0, 90, 180, 270, 360])
a = raw_a.rotate(rot_deg)
# Tilt image
tilt_deg = random.randint(-8, 8)
a = a.rotate(tilt_deg)
# Flip image
flip_x = random.randint(0, 1)
flip_y = random.randint(0, 1)
a = a.flip(flip_x, flip_y)
augumented.append(a)
# Show first augumented image.
augumented[0].show()

Imagine you don’t know what a web_service is, but you’ve heard someone talking
about them and you are interested in knowing more about them. You click the
link in the previous sentence and are told
Web services today are frequently just Application Programming
Interfaces (API) or web APIs that can be accessed over a network,
such as the Internet, and executed on a remote system hosting the
requested services.
That didn’t make any sense to you, but you continued reading and made it to
The W3C defines a “web service” as “a software system designed to
support interoperable machine-to-machine interaction over a network.
which started to make a bit of sense. However, as you weren’t particularly
enlightened yet, you enter ‘What_is_a_webservice’ into Google and read other
‘explanations’ like the one from Webopedia:
The term Web services describes a standardized way of integrating
Web-based applications using the XML, SOAP, WSDL and UDDI open
standards over an Internet protocol backbone. XML is used to tag the
data, SOAP is used to transfer the data, WSDL is used for describing
the services available and UDDI is used for listing what services are
available. Used primarily as a means for businesses to communicate
with each other and with clients, Web services allow organizations to
communicate data without intimate knowledge of each other’s IT
systems behind the firewall.
 This is a very bad thing, because it discourages people from
learning: if it is impossible to find a decent introduction to a subject,
surely it’s either too hard or too obscure?
There are several possible explanations for why these introductions are so bad:
I’m not sure which of these reasons is dominant, but even if all of them hold
for the authors: surely there is at least one editor that realizes it should be
thumbed down and can explain how and why?
What motivated me to write this article was the fact that, for the first time,
I had to use WS-Addressing and WS-Security in a web service client and the
first question that came to mind was: “why do we need these”? After figuring
that out, I concluded that the explanations on Wikipedia and other high-ranking
search results really didn’t give me the answers I was looking for.
Firstly they suffered from the problems described in the beginning of this post, but
secondly: the explanations never went into the ‘why’ of these things. They all
just explained the ‘what’ and the ‘how’. This is what the Wikipedia
introduction on WS-Addressing currently says:
WS-Addressing or Web Services Addressing is a specification of
transport-neutral mechanisms that allow web services to communicate
addressing information. It essentially consists of two parts: a
structure for communicating a reference to a Web service endpoint,
and a set of Message Addressing Properties which associate addressing
information with a particular message.
 Why wouldn’t
something like the following do?
The motivation for WS-Addressing is that you want to allow clients to
invoke a web service using address A, while the web service itself
lives at address B. This allows you to, for instance, use address A
as a front door to web services at addresses B, C, D and E, while
having the software at address A perform routing, validation,
authentication, etc. for all these other web services. It also allows
you more freedom in your web service addresses, because they don’t
need to be URL’s that are reachable over the network: only address A
needs to be ‘real’.
Secondly, a FAQ or the like should answer the obvious question: can’t you solve
this in some other way?
Of course you can come up with your own scheme to obtain the same
goal, but one downside to that is that the software at address A
would have to be able to deal with different homegrown
implementations of the same general principle, if it were to allow
access to web services of different origins. Another downside is that
you may initially overlook functionality, that proves harder to ‘tack
on’ later. That’s why Microsoft, IBM, Sun, BEA and SAP, under the
auspices of the W3C, came up with a single standard, which contains
specifications for all scenarios they could think of.

Ok, this is starting to get on my nerves. Venturebeat is reporting that you can now choose to have parts of your items within Facebook public, aka visible for everybody. Facebook themselves go into a bit more detail:

Just go to your privacy page and change the settings you want to the new "Everyone" option. You can opt to make one or all of the following profile elements more open: Profile, Status Updates, Links, Wall Posts, Basic Info, Personal Info, Education Info, Work Info, Photos of You and Videos of You.

Yehaa! Another public profile. Another bit of status updates. Another place to copy more of the same. Can all you people really start deciding what it is going to be? Xing is for my professional life really, and I am very happy that they are sticking with that focus. Facebook was for my general social graph / friend connections that is beyond just business. I really like it to be more private because it can be, as it has my friend connections. I am putting a lot of stuff into Facebook, which I am also putting into thylmann.net by the way, so it is very similar to FriendFeed there for me (Oooops, another one there. ;)). I am slowly not able to keep track anymore people!!! It would be no problem if they were all copy cats to start out with but they were freaking different!!! Grrrrr….!
At least they should all give me the option to keep everything out of the SE indizes even if it is public. And this again pushes the importance of something that is portable and really mine, e.g. my own Noserub install at thylmann.net. Because you know what? My ID, My Everything, My Life is freaking MINE. And that means that I need to be in full control and need to be able to decide what people are pointed to and move it, with all the content.
So I want a few things:

Give me the option to lock out Search Engines

Give me a full data export of my data in XML

Somebody build the perfect [life aggregator](http://blog.thylmann.net/2008/12/28/self-generated-content-infrastructure/)... I think Noserub is a good start

Because you know what? These things are slowly not anymore about connecting me with my friend but to keep a log of my life, and that is something completely different and something that needs to be extremely more portable.
