Perspective Correction For Image Processing
2015
Abstract The paper proposes an algorithm for applying the perspective correction of images containing human faces. Based on the coordinates of the two eyes, of the center of the mouth and of a point on the line of the mouth, one can estimate the angle of inclination of the face. After applying the perspective correction, the area corresponding to the face can be used by a face recognition algorithm based on aspect in order to improve the good recognition rate.
Adaptivity in E-Learning Systems
2018
Abstract The differentiated designing of lessons from the virtual environment can have beneficial effects on the student. In order to achieve the objectives proposed in the course, the content should not only meet the student’s expectations but must be designed adaptively according to the defining elements of each learner. Adaptability in content is an essential factor in maintaining motivation, involving the student, and engaging him/her in the study. The paper analyses approaches for the adaptive building of content by identifying the elements that can influence the achievement of the objectives - motivation, expectation, learner’s style, a priori knowledge
