In this review, we’ll look at the course and the academy, helping you to decide if it is a good option for you. We will end with a look at the job market and its predicted future based off of analysis and stats. First, we will look at a bit about the academy.


Udacity and Accreditation

Udacity has been around since 2012. It started off as a platform that included multiple introductory level computer science courses for enthusiastic learners. Its success would come as several powerful companies in the industry would hop on board, partnering with the academy to develop certification courses that equipped graduates with enough knowledge to land entry-level jobs.Now, as you can already tell, the academy has grown into a full-fledged academy where learners have options from the most basic knowledge to very advanced specified computer sciences concept sand techniques.


Apart from the knowledge needed to be a success in the field, each nanodegree offered by the academy comes with a few extras. It is their goal to help learners succeed in every way possible, perhaps the reason behind these nanodegree perks. These include:


  • A Mentor

There for you in the wake of any kind of problem. Whether it be technological or something to do with the course, the mentors selected for you are dedicated to keeping you on track and motivated so that you have nothing that can possibly get in your way.


  • Flexible Learning

While the academy offers an estimate of how long they believe the course will take you, you have all the time you need. You are able to save your place and login when you’d like, creating your own hours and schedule as you see fit.


  • Real Industry Projects

Some of these courses are made in collaboration with top companies in the industry. They have provided the academy with projects and materials that mimic real problems and projects that these companies attempt to solve.


  • Career Services

Included at the end of each certificate course is a spot in the Udacity database. This is a powerful tool that attempts to put graduates in contact with recruiters. To prepare graduates and current learners for the job-hunting process, there are mock interviews and help with resumes to get graduates ready and prepared for the big day.


Udacity Computer Vision Nanodegree Prerequisites

So, what do you need to begin? The prerequisites are pretty specific and include intermediate knowledge and familiarity with a number of programs and concepts including:


  • Python and TensorFlow
  • Statistics and probabilities
  • Machine learning techniques
  • Code written by others
  • Nestled loops


Without these, you might not have the knowledge base necessary to grasp on to a few of the more complex ideals presented throughout the course. It could be a good idea to take a step back and build that knowledge before taking on the course to ensure your success.


Udacity Computer Vision Nanodegree Instructors

Besides the extras, Udacity attempts to stamp out the competition with their powerhouse team of instructors. We must admit, the staff is quite impressive, with years of experience and work with industry giants. For this course the instructors include:

Udacity Computer Vision Nanodegree Course

Without further ado, let us get to the course. The entire course is broken down into three sections. Each of these is filled with information that builds up to a final application that learners will need to complete at the end of each section. The three sections and their contents are:


Intro to Computer Vision

From the get go you’ll work with image processing essentials. You’ll begin to see the powers that deep learning provides when combined with computer vision, beginning with image processing, extraction and import. At the end, you’ll work on a project involving facial keypoint detection.


Advanced Computer Vision and Deep Learning

In this section you will start to see how deep learning architectures are developed and how they come together to allow automatic image applications. From the knowledge gained dealing with CNN and RNN, at the end,you’ll work with automatic image captioning.


Object Tracking and Localization

In this section, you will see how to use technology to track and locate objects over time. These are the same techniques that those in the field use in creation of self-driving cars, drones, and navigation systems. This section will end with a hands-on project to create and optimize a tracking system that uses landmark detection.


The Time

We know you’re probably thinking, how long is all this going to take me? The truth is, the academy estimates a much shorter time than you may be thinking, 3 months to be exact. This estimate comes with the idea that you’re dedicating anywhere from 10 to 15 hours per week. As we mentioned above, you can take all the time you need, only needing to stick to certain deadlines for projects once you get to that section of the course.


An important note about the time it takes is that it directly affects the price of the course. This might change up your way of thinking and make you take your intensity and pace differently. We will talk more about the price and how it changes with the time it takes to complete the course in the section below.


Udacity Computer Vision Nanodegree Price

Udacity has a unique way of charging for the course. This is an attempt to make it affordable for more potential students, giving them a few options to choose from. These options include a monthly amount set at $399 per month. When you pay per month, you’ll be given full access for that period and charged again once one month has passed. The second option comes from the academy’s estimate, adding in a discount if in fact you pay for the full course estimated access up front. In the case of this course, that would come out to a little under $1200.


Currently, the site is running a promotion which comes with a free month no matter which way you pay. The bundle option is still cheaper in the long run, as it still comes with the 15% discount added in. When deciding which option would work best for you, it is best to take a look at your current schedule, deciding how much time you can dedicate to the course. Then, set a schedule that you can keep up with and give yourself a little ‘wiggle room’ just in case. Then, you can decide whether it would be more beneficial for you to take it month by month or go ahead with Udacity’s recommendation.
