identify these programs from their icons

Hi, I (Myself a senior PHP, ASP.NET programmer using C# and VB) have a team having experience of more than 10 years in developing web and mobile applications. I have a team of expert programmers who write robust and bug-free codes at the very first instance. After seeing our quality of work and the cooperation offered to you even after the work has been delivered to you, you’ll come to us again and again to avail our services. I read through the job details extremely carefully and I am absolutely sure that I can do the project very well. I can achieve the results that you are asking for within your timeframe and budget. I am confident I can exceed your expectations and I would love to work on your project. Thanks, Priyanka

Hi. I have checked the icons you have sent and I can identify these applications for you. Contact me and we can get it done in a few minutes!

That`s too easy. I will provide link to each program site. .

Hi JI - IntelliJIdea IDE for programming mostly Java Last Graph Icon - Matlab I will be happy to research the rest for you if awarded the project for $ 30. I'm a skilled programmer in both Java and Android in case there is more assignments. Thanks, Isaac

Sir, As per my understanding you require image matching algorithm to identify softwares based on thier icons. I can provide you such software. I have expert level skills in image analysis and processing algorithms. Looking forward to work with you.

I can already name two of given icons. Another two will be known after a brief research what shoud not take more than 3 days.

From left to right: 1- Yandex Browser 2- IntelliJ IDEA 3- ??? 4- Matlab Problem with third one is it isn't what I'd call unique, I can try one more time later on.

PhD Student major in Computer Science. Did research about python image processing so I know lots about python image lib and I can do this quickly and easily.
