What is a lens?

Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

This content is ...

Birdcall Identification: Matlab GUI

Module by: Robert LiKamWa. E-mail the author

Summary: Description of a MATLAB GUI that identifies bird calls within audio wave files.

Matlab Bird Call Identification Program

Matlab GUI

The group created a MATLAB Graphical User Interface (GUI) to implement the birdcall identification algorithms.

Figure 1
Figure 1 (GUI.png)

Our GUI was able to load in audio files, play them, and display the result of convolving the audio signal with a specific filter. It also produced a bar graph of the maximum of the convolution result for each filter. This would graphically show us not only which birdcall the audio signal contained, but also how confidently the program was reporting one birdcall over another.

The GUI has the ability to choose whether or not to use our frequency content checking algorithm.

My Favorites (?)

'My Favorites' is a special kind of lens which you can use to bookmark modules and collections. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need an account to use 'My Favorites'.
