Recognition of facial expressions

یک کد متلب میخوام نوشته بشه که دیتاهایی که دارم تشکیل شده از تصاویر است که هر شخص دو تصویر یکی خندان یکی جدی دارد که هر تصویر رو که به صورت رندوم بالا میاره تشخیص بده خندست یا جدی توضیح کلیشو به صورت انگلیسی هم میفرستم : Project 5: Recognition of facial expressions Objective: You have a database of faces shot for each subject with two expressions: serious and smiling. The goal is to build a system for the automatic recognition of facial expressions (serious/smiling). Method: - Inspecting the structure of the dataset (PCA or similar) - Develop binary classifiers (Bayesian and logistic classifier models) that correctly associate expression (serious, smiling) with face. - Analyze the classifiers performance (% of correct decisions, sensitivity, specificity, AUC) and determine what classifier model is best. - Use LDA to identify which image features are most important for discrimination. Bonus: Using the same approach, build a classifier that can also distinguish the person's gender in addition to their expression. Data: http://fei.edu.br/~cet/facedatabase.html; in particular, see the dataset frontalimages_manuallyaligned_part1
