This study presents a new color-depth based face database gathered from different genders and age ranges from Iranian subjects Using suitable databases it is possible to validate and assess available methods in different research fields This database has application in different fields such as face recognition age estimation and Facial Expression Recognition and Facial Micro Expressions Recognition Image databases based on their size and resolution are mostly large Color images usually consist of three channels namely Red Green and Blue But in the last decade another aspect of image type has emerged named depth image Depth images are used in calculating range and distance between objects and the sensor Depending on the depth sensor technology it is possible to acquire range data differently Kinect sensor version 2 is capable of acquiring color and depth data simultaneously Facial expression recognition is an important field in image processing which has multiple uses from animation to psychology Currently there is a few numbers of color-depth RGB-D facial micro expressions recognition databases existing With adding depth data to color data the accuracy of final recognition will be increased Due to the shortage of color-depth based facial expression databases and some weakness in available ones a new and almost perfect RGB-D face database is presented in this paper covering Middle-Eastern face type In the validation section the database will be compared with some famous benchmark face databases For evaluation Histogram Oriented Gradients features are extracted and classification algorithms such as Support Vector Machine Multi-Layer Neural Network and a deep learning method called Convolutional Neural Network or are employed The results are so promising
