Due to the large number of classes and small inner-class distance, this problem is known as a hard classification problem.
In this paper, a comparison between holistic and part-based approaches has been made and most of the previous methods in each category have been reviewed. In addition, a new part-based method is proposed which tries to overcome some of the hard challenges in this area. This method operates on meaningful parts of vehicle like lights, grilles and logo for distinguishing of different classes. The Histogram of Oriented Gradients (HOG) and Support Vector Machine (SVM) have been used for feature extraction and classification tasks respectively. For evaluation purposes, a dataset including 352 images from frontal and rear view of eight different classes of vehicles have been prepared and fully marked based on their parts. The experimental results show the effectiveness of the proposed part-based approach in comparison to the traditional approaches. The proposed method achieved 95.4% accuracy on frontal view and 100% accuracy on rear view images.After vehicle detection and vehicle type recognition, it is vehicle make and model recognition (VMMR) that has attracted researchers attention in the last decade.

In fact, determination of this region has been like a bottleneck, gaining a significant computational energy. As a result, selection of suitable and fast approaches, under these circumstance, may enhance the performance of the recognition system. In this paper, a review was provided on the recent studies carried out in this field of research and few of the famous and friendly approaches conventionally used in the strong recognition systems were introduced and applied on the dataset of PASCAL VOC, ImageNet and COCO. The results obtained indicated that the multiclass combinatorial grouping (MCG) method with the region-convoulational neural network (R-CNN) can provide the best results with the efficiency of 57%, 54% and 41% on the dataset of PASCAL VOC 2007, ImageNet 2013 and COCO 2014 respectively.According to the studies carried out in recent years, determination of the regional proposal is one of the crucial steps in detection and recognition of the objects included in an image.

However, the required data for prediction is not available for every interested location. So, different models have been proposed for air pollution prediction. The feature selection (among 20 features given in Meteorology Organization data) was performed by binary gravitational search algorithm (BGSA) in this study and 10 features were selected. An artificial neural network (ANN) was used in this study for air pollution prediction. This ANN was trained using chaotic gravitational search algorithm (CGSA). In a comparative study, the performance evaluation of this neural predictor was performed when other methods were also used for ANN training. These methods were error back propagation, standard GSA, artificial bee colony, particle swarm optimization, and hybrid of genetic algorithm and simulated annealing. Experimental results showed the superior performance of the proposed BGSA-CGSA method used for feature selection and ANN training.Prediction of urban air pollution is an important subject in environmental studies.

Changeable nature of feed, interaction of variables and weakness of accurate measurement equipment have made the development of monitoring methods and continues control of flotation circuits to an important issue. Today with the advance of technology, machine vision systems based on image processing methods are considered a rapid, cheap and safe detection device in mineral processing industries. The appearance of flotation froth surface consists of significant information process which easily distinguishes the process operation condition. Size distribution of froth bubbles is the reflection of froth stability and velocity and is the best criterion for the efficiency estimation of flotation operation.
