1
Explain what region proposals are
Recall
Object detection answers what and where
Object detection answers what and where
Two-stage detectors (R-CNN family) exist
Two-stage detectors (R-CNN family) exist
One-stage detectors (YOLO, SSD) exist
One-stage detectors (YOLO, SSD) exist
Before detecting objects, the system must first decide where to look.
Analogy
Imagine you are searching for a lost wallet at home.
You don’t look in Impossible places
Look in places where a wallet cannot be
Blind Search
Now comes to Intelligent Search
Analogy
Intelligent Search
Focus on tables, beds, and drawers
Ignore unlikely locations
Got the wallet
Same as like this Region proposal techniques helps system to focus only on likely object regions

Inside the Concept
How can you combine two arrays?
In Javascript, we can combine two arrays by mean of concat() method
Syntax:
arr1.concat(arr2)
let arr1 = ["a", "b"];
let arr2 = ["c", "d"];
let result = arr1.concat(arr2);
["a", "b", "c", "d"]
Note:
Returns a new array
Original arrays remain unchanged
How can you copy elements from an array without altering the original?
Syntax:
arr.slice(start, end)
let arr = ["a", "b", "c", "d"];
arr.slice(1, 3);
//includes start index
// omits end index
["b", "c"]
Note:
Returns new array
In Javascript, use the slice() method to copy part of an array without altering the original.
