The segmentation aims the partitioning of a digital image into segments/objects in order to simplify its analyze. Its comprehensive application makes it an important section of computervision studies where thresholding is one of the most important techniques. This paper proposes the application of a genetic algorithm associated with a thresholding method in a way that it makes more practical the location of optimal thresholds in view of the fact that the expansion in multiple thresholds of already consecrated methods to perform this processing might be too memory consuming and time exhaustive to the system. A comparison between values reached by the proposed method and Otsu's method are presented for one and two levels showing good results, in addition to the application and results in higher levels of the proposed algorithm which are visual satisfactory to distinguish the original objects by human vision with low range variations of the value.

Facial expression recognition is a hot research direction in the field of pattern recognition andcomputervision. In this paper, the images of customer's face are used to detect the facial expression in them to enhance the customer based services. The convolution neural network using the VGG-16 architecture is used as the deep learning model which extracts essential features in an image and enables us to recognize the expression of the customer. A customer service system architecture is designed using two neural networks, a convolution neural networks using the VGG-16 architecture our baseline and the Google cloud platform vision application program interface to explore the needs of different models based on the client usage.
image encryption is different from that of traditional texts or binary data because of some inherent properties of images such as large data capacity, i.e., enormous size and high redundancy (statistical and psycho-vi...

Moving target tracking has always been an important research direction in machine vision. Based on the careful study of the compression tracking algorithm, this paper proposes an improved algorithm for collecting a large number of samples in the tracking phase, using the positive and negative classifiers for judgment and large computational complexity: In the previous frame tracking result of the video, the window with the larger cross-correlation value of the target frame is used as the optimal tracking position in the corresponding region of the current frame, thereby reducing the calculation amount. The results of computer simulation experiments show that the algorithm improves the operation speed without affecting the tracking accuracy.
