Signals and image processing/analysis -- Learning Resources

I'm at a mediocre university I don't belong at and can't really transfer at this point unless a great university is willing to break its own rules about deadlines for me for this fall(connections, anyone?!). I suppose I'll just have to wait for grad school (should be starting in spring '14), but this is very frustrating.

So, I'm studying signal and image processing/analysis, and the curriculum is so boringly easy. I know the material isn't really as easy as the courses I've had, so, what are some things I should know and how should I go about learning them?
Also, where should I learn them? (best schools for this discipline)
Are there youtube videos on the material or free textbooks online?
Which disciplines of math that aren't typical for a EE undergrad to take are involved in the higher level signal and image analysis, or at least would up a GRE score and help with grad school?
(I've aced the calc series, linear algebra, DifEQs, and complex analysis)

1. The first and most important step is to find a good textbook. MIT OpenCourseWare, Khan Academy, and Coursera are all great resources for finding free textbooks on signal and image processing/analysis. Additionally, you can find many free textbooks online at sites such as LibreTexts and Textbook Revolution.2. Once you have a good textbook, practice problems are the best way to learn the material. Reviewing practice problems from the textbook or from other sources (such as online problem sets or sample exams) will help you to understand the concepts and apply them to real-world scenarios.3. To further supplement your learning, video lectures are a great resource. YouTube, Khan Academy, and MIT OpenCourseWare all offer excellent video lectures on signal and image processing/analysis. Additionally, there are numerous online courses that are specifically designed for this field, such as Coursera’s “Signal and Image Processing Specialization.”4. As for additional disciplines of math that would help you with signal and image processing/analysis, it is best to consult with an advisor or professor in the field. However, some disciplines that may be helpful include statistics, probability, optimization, machine learning, linear algebra, and numerical analysis.
 

1. What is the difference between signals and images in terms of processing and analysis?

Signals and images are both forms of data that can be processed and analyzed using similar techniques. However, signals are one-dimensional data that represent changes in a single variable over time, such as sound waves or ECG signals. On the other hand, images are two-dimensional data that represent visual information, such as photographs or medical scans. This difference in dimensionality affects the types of processing and analysis methods used for each type of data.

2. What are some common techniques used in signal and image processing/analysis?

Some common techniques used in signal and image processing/analysis include filtering, feature extraction, and classification. Filtering involves manipulating the data to remove noise or enhance certain features. Feature extraction involves identifying and quantifying specific characteristics of the data. Classification involves categorizing the data based on these features or other criteria.

3. How are signals and images represented and stored for processing and analysis?

Signals and images can be represented and stored in various formats depending on the specific application and data type. For signals, common representations include time-domain and frequency-domain representations, such as waveforms and spectrograms. Images are typically represented as arrays of pixel values, with each pixel representing a specific color or intensity value.

4. What are some applications of signal and image processing/analysis?

Signal and image processing/analysis have a wide range of applications in various fields, such as biomedical imaging, telecommunications, and computer vision. Some specific examples include medical image analysis for disease diagnosis, speech recognition for communication technology, and object detection and recognition for autonomous vehicles.

5. What resources are available for learning about signal and image processing/analysis?

There are many resources available for learning about signal and image processing/analysis, including textbooks, online courses, and tutorials. Some popular textbooks include "Digital Image Processing" by Rafael C. Gonzalez and Richard E. Woods, and "Digital Signal Processing" by John G. Proakis and Dimitris G. Manolakis. Online courses and tutorials can be found on websites such as Coursera, Udemy, and YouTube.
