A short intro about Google Vision

-
The Mobile Vision API has detectors that let you find objects (face, smile, eyes etc) in photos and video.

Detect Faces
The Face API detects human faces in photos, videos, or live streams. It also finds and tracks positions of facial landmarks such as the eyes, nose, and mouth.



Face detection is the process of automatically locating human faces in visual media (digital images or video).
A face that is detected is reported at a position with an associated size and orientation.
Once a face is detected, it can be searched for landmarks such as the eyes and nose.

Face recognition inspects if two faces can resemble to the same person.
Note that at this time, the Google Face API only provides functionality for face detection and not face recognition.

Face tracking extends face detection to video sequences. Any face appearing in a video for any length of time can be tracked. That is, faces that are detected in consecutive video frames can be identified as being the same person. Note that this is not a form of face recognition; this mechanism just makes inferences based on the position and motion of the face(s) in a video sequence.

A landmark is a point of interest within a face. The left eye, right eye, and nose base are all examples of landmarks. The Face API provides the ability to find landmarks on a detected face.

Classification is determining whether a certain facial characteristic is present.
For example, a face can be classified with regards to whether its eyes are open or closed.
Another example is whether the face is smiling or not.


**Will Come up with next GOOGLE VISION API definition after a short while.

Iterating a HashMap

-
We know that, Java HashMap class implements the map interface by using a hashtable. It inherits AbstractMap class and implements Map interface. The important points about Java HashMap class are: A HashMap contains values based on the key. It contains only unique elements. It may have one null key and multiple null values. It maintains no order. Many times we have to iterate hash map for key or value or both key&value. Here is code block to iterate for the same... If you're only interested in the keys, you can iterate through the keySet() of the map:   Map < String , Object > map = ...; for ( String key : map . keySet ()) { // ... } If you only need the values, use values() : for ( Object value : map . values ()) { // ... } Finally, if you want both the key and value, use entrySet() : for ( Map . Entry < String , Object > entry : map . entrySet ()) { String key = entry . getKey (); Object value ...
