I hope that this helps students, pupils and others. #StartLearningMathematics #Maps (This explanation fits to lectures for students in their first year of study: Mathematics for physicists, Mathematics for the natural science, Mathematics for engineers and so on)
The image of a function sounds complicated but it's not as bad as you think. It's really just the mapping of an element in one set to another element in another set. The pre-image is then the reverse (or inverse) of that same process - all of this is explained in the video above.

Full cryptography playlist : 🤍 These video mentions important concepts of Hash (and also other sections of cryptography). What is a collision ? What is preimage resistance ? What is second preimage resistance ? What are preimage and second preimage attacks ? How collision differs from second preimage attacks. Is sha-1 really broken ? Is MD5 really broken ? Is there any known preimage or second preimage attack against known hash like MD5 or SHA-1 or others. Why you should not use these hash for passwords. Can you use SHA-1 for passwords hashing in your website. How was shatter attack actually done. What is chosen prefix attack collision attack. Many such questions answered in this video. Very important video when cryptography is concerned. #collision #preimage #resistance #hash
Please Subscribe here, thank you!!! 🤍 Preimage(Inverse Image) Explanation and Intersection of Sets Proof. Given a function from X to Y and subsets A and B of Y, in this video we prove that f^(-1)(A n B) = f^(-1)(A) n f^(-1)(B). For a subset A of Y, inverse image or preimage of A under f is the set of all elements of X which get mapped to A; i .e., f^(-1)(A) = {x in X | f(x) in A}. I hope this video helps.
Images are snapshots of the entity’s attributes, before and after the core system operation One of the best uses for this is in update plug-ins. As mentioned before, update plug-in target entity only contains the updated attributes. However, often the plug-in will require information from other attributes as well. Instead of issuing a retrieve, the best practice is to push the required data in an image instead. Comparison of data before and after. This allows for various audit-type plugins, that logs what the value was before and after, or calculating the time spent in a stage or status

This video illustrates how a function induces an "image" function from the subsets of the domain to subsets of the codomain as well as a "preimage" function from the subsets of the codomain to subsets of the domain.

0.3 sq km point cloud of Tuniu River in Taiwan classified using Preimage software in 3 minutes. We got a classification accuracy of 82% compared to ground truth (manually annotated). When comparing ground vs non-ground classification, the accuracy was just above 89%. This point cloud was not used for training our AI models. Dataset courtesy: 🤍 🤍preimage.ai
