How to create Enterprise Architect online repository for free on AWS

Estimated time: 1h Difficulty: Easy Requirements: Valid credit card and Enterprise Architect license. Intro If you are IT Architect or Analyst like me, you have probably came across a program called Enterprise Architect.

Slovak NLP resources

Lately, I have been working on a new interesting project that utilizes NLP tools and resources in Slovak language to bring a real value to customer. So far it has been quite challenging, since there are very little resources, corpora and tools available. I have decided that it is best to investigate and find all the usable NLP tools and resources (somewhat usable for slovak language) on the internet and compile them together on github and release my tools as open source so we can move forward together. You can find the links here: https://github.com/essential-data/nlp-sk-interesting-links Feel free to contribute and…

Copy CSV (Excel) table to Jira

Jira description editor is still using Jira markup for tables and it is really hard to copy paste complete tables from csv/excel to Jira. There are online tools available to help with this manner by providing input where you copy table from excel and it produces Jira Markup table. I have developed my own for these reasons: Security. My implementation does not send or store any data and is provided by secure webserver (https). You can evaluate this by monitoring server communication and inspecting the source code. Multiline support. My implementation uses PapaParse, that supports multiple lines in excel cell….

How to do face recognition in OpenCV and how to improve it by aligning faces

After a long time here I come with some great news. In my semestral project for computer vision I worked on application which can improve face recognition by rotating faces so they align with training set.

FacePreview on Android with native libraries

Android has its own face recognition and we don’t need OpenCV to find faces on pictures or while shooting with camera. In this example I used FaceDetector to find faces on Bitmap image which I had to create from Raw data. The biggest problem of this solution is the conversion. Since FaceDetector supports RGB_565 and many android cameras support only YUV. I tested this on my Huawei Honor 2 with NV21 bitmap image type. If your device supports other image format feel free to edit code and/or post your conversion function in comments or ask for help if needed. Second…
