Hello everyone.
I am new in image processing,I am currently try detecting and characterizing a brain tumor glioma (HGG.LGG) in multimodal MRI (T1.T1 + C.FLAIR...).
can anyone help me how I start this job and if anyone has images of this tumor (multimodal MRI of the same patient)?Please help me.
thank you in advance.

It depends on your knowledge of image processing.

1. If you are new to this field, in general, it has no sense to start with coding in i.e. Matlab cause you have to understand what you are doing. Start with this excellent book https://www.amazon.com/Digital-Image-Pro... It is very expensive but the bible in image processing. I didn't find any similar to this one. The new version covers very detailed new concepts like convolutional
neural networks.

2. Otherwise, if you are familiar with some concepts in image processing like histograms, filters, colors, feature extraction etc. you can try algorithms and concepts in Matlab first and transfer to another language like C++, Python etc. One very good source for Matlab libs for reading and converting MRI, DICOM and NIFTI images is this one: https://www.mathworks.com/matlabcentral/...
It took me some time to figure out how to read and edit images like nifti ones, but it is not so difficult if you have understood the concept.
