Self-compacting mortars are achieving a great deal in the construction industry due to their remarkable characteristics and due to their advantages over conventional concrete. The main drawback associated with self-compacting mortars is the high cost associated with the ingredients used in the production of self-compacting mortars. This research ai...

Face recognition system is an important area of human biometrics and a successful application of pattern recognition. Variable illumination conditions in face images are main obstacle in face recognition systems. To deal with this problem, this paper presents robust illumination-insensitive preprocessing, Zernike Moments-based feature extraction an...

Lung cancer is the abandoned growth of abnormal cells that instigate in one (or) both lungs; usually in the cells that line the air passages. The anomalous cells segregate rapidly and form tumors but not as a healthy lung tissue. There are three major types of lung cancer. They are NSCLC,SCLC and lung carcinoid tumors. Staging lung cancer is based...

... In addition to being rotational invariants, they can be made into scale and translation invariants after certain geometric transformations. PZMs have been used in numerous machine learning and image analysis applications, such as cephalometric landmark detection [17], Alzheimer's disease detection ( [18][19][20]), medical image retrieval [21], detection of tumors and brain tumors ( [22][23][24]), facial expression [25] and facial age recognition [26], facial recognition ( [27,28]), and other industrial applications [29]. ...
... The OSP algorithm proposed here is based on the Genetic Algorithm (GA) [34][35][36]. The choice of a heuristic optimization method is due to the characteristics of the function to be minimized, presenting a complex shape with many local minima. ...
