Non existing links in README.md

[GoulartNogueira]

Problem:

At the main README, there is a table with a few internal links:

Link Status	Link
⚠️ Non-existing link	Detection
✅ Working	Alignment
⚠️ Non-existing link	Recognition
⚠️ Non-existing link	Parsing
⚠️ Non-existing link	Matting
⚠️ Non-existing link	Headpose
❓ Just a sketch	Tracking
⚠️ Non-existing link	Assessment
⚠️ Non-existing link	Utils

Most of those links will point to some non-existing README file.

Fix

For each link, we should either:

1. Create the file
2. Fix the link to point to an existing file
3. Remove the link
