Hire a Matlab and Mathematica Engineer

The task is separated into two parts and each part has 3 sections as follows: Part 1 Section A: • Give a brief description of the perceptual hashing technology and discuss its applications. • Explain how robust and fragile watermarking can be used to solve legal and ethical issues related to digital images and videos. Section B: You are provided with a test image saved as TIF file named ‘[login to view URL]’. For the purpose of image copyright protection, you are required in this section to implement a one-bit watermarking system in the wavelet domain and a similar watermarking system in the DCT domain as follows: Section C In this section, you are required to apply the following manipulations on the watermarked image in both wavelet and DCT domains and check the detection of the watermarks. Complete the following table and interpret the results. Part 2 Section A Discuss the main similarities and differences between Artificial Neural Networks and Decision Trees. Section B Explain why, in supervised machine learning, multiple samples from each class are required in the training phase. Section C The implementation of a gender classification system using an Artificial Neural Network is given in Matlab. The Matlab function ‘getFeatureVector.m’ extracts 64 features from any input colour image by using the grey scale plane only in the Discrete Cosine Transform (DCT) domain. There are two types of training images: male and female images which are stored in two folders ‘Male’ and ‘Female’, respectively. The extracted features for both male and female images will be used to train the classifier with ‘ANN_training.m’. Once the classifier is trained, it can be evaluated on test images stored in folder ‘test_gender’. This is implemented via the Matlab code ‘ANN_testing.m’ where the default image is ‘[login to view URL]’. The idea is to verify the gender each face image according to the trained classifier. If a female image is classified, the system will display a message ‘female’. Otherwise, the message ‘male’ is displayed. The files that must be used are included in the [login to view URL] and the detailed description of the task can be found in the task brief. As well as other supporting files.
