Face Expression Classification Using Neural Network and PCA algorithm

The purpose of this article is to shed light on the mechanism and the procedures of a program that classifies an input face into any of the six basic facial expressions, which are Anger, Disgust, Fear, Happiness, Sadness and Surprise, in addition to normal face. This program works by apply PCA- principal component analysis algorithm, which is applied of one side of the face, and depends, on contrast to the traditional studies which rely on the whole face, on three components: Eyebrows, Eyes and Mouth. Those out-value are used to determine the facial feature array as an input to the neural network, and the neural network is trained by using the back-propagation algorithm. Note that the faces used in this study belong to people from different ages and races.

Assess the performance of the diagnosis ways of diabetic retinopathy

Considered the diagnosis of diseases using image processing is one of the most important areas of image processing techniques used in the medical field, Where is the digital data in the field of ophthalmology focus of researchers for automatic detection of some important diseases such as diabetic retinopathy (DR). And is defined as damage to the retina of the eye comes as serious complications and on the human body complications resulting from diabetes in the long term and is considered one of the most important causes of blindness in the world and cause serious damage to the retina. The research aims to Assess the performance of some of the methods used in the diagnosis of diabetic retinopathy by revealing one of the most important accompanying pests him in the retina of the eye and is the exudates and through diagnosed in images digital fundus through image processing techniques where this detection process contributes in helping to early detection.

A Proposed Approach to Reduce Digital Image Processing Time in Real Time Applications

This research introduces a new approach to reduce time execution of processing programs, by reducing the amount of processed data, especially in applications where the priority is to the execution time of the program over the detailed information of captured pictures, such as detection and tracking systems.

Develop a Parallel Processing System to Recognize the Deaf and Mute Gestures and Apply it based on FPGA

In this paper, we processed an array which represents the human hand image to get the characteristics of this image. So, we used FPGA technique, and the processing operation is partitioned into three threads which is carried out in parallel. Each thread is carried out using the pipeline technique by partitioning thread into four segments. After that, we evaluated the speedup that we get in result of using the pipeline technique and the parallel threads. So, we have the possibility to design an embedded system integrated into chip (SoC), and using the mobile phones as integral devices support the software and hardware resources.

Automatic Facial Expression Classification Using Image Processing Technique ( Fear – disgust – sadness – Surprise – Anger – Happiness – Natural )

This paper presents an algorithm for designing a system that classifies standard human facial expressions which are fear , disgust , sad , surprise , Anger , happiness , natural expression . The facial expression that is presented in the input image of the system can be classified depending on extracting appearance features , then they entered into neural network to complete the classification process using Matlab as a programming language.
