Abstract:
Machine Learning has a practical and profound application in intelli j gent traffic management systems. ITS is a very broad terminology in which includes
vehicle detection, classification, monitoring, surveillance, license plate recognition,
etc. Vehicle classification playing a vital role in the intelligent transportation sys tem for traffic management and monitoring. This study is aimed at the fine-grained
classification of vehicles using convolutional neural networks. To accomplish the
task there are lots of challenges involved in which the biggest challenges are Inter class and Intra-class similarities between the make and models of vehicles, lightning
conditions, background, shape, pose, a viewing angle of the camera, speed of the
vehicle, the size of the vehicle, color occlusion and environmental conditions. There
are three different datasets are used in this research BMW-10, Stanford Cars, and
PAKCars.The BMW-10 and Stanford Cars datasets are available open-source, while
PAKCars dataset is self-generated especially for fine-grained classification of cars in
Pakistan to analyze the implementation of research. The system will work on ma chine learning which is further divided into two steps namely training and testing.
Initially, the system will be trained on the training dataset and afterward, the per formance of the system will be tested using the test dataset. In the training part of
the system, four different DCNN models are Mobilenet, InceptionV3, VGG-19, and
ResNet-50 used. Each model is trained on all three datasets (BMW-10, Stanford
Cars, and PAKCars).
A total of 10 classes are evaluated in the BMW-10 dataset having a total
of 511 images whil 196 classes are evaluated in Stanford Cars datasets having 8144
training images and 44 classes evaluated in PAKCars datasets which have total 1000
images. To perform the classification of the fine-grained vehicle DCNN models are
used. The result acquired after processing reveals the results under the performance
of true classification ResNet-50, VGG-19, inception-V3, and Mobilenet respectively.
Mobilenet and InceptionV3 models consume less computational power and are less
accurate, but VGG19 and Resnet50 are more accurate, because of their higher num bers of layers and architecture that make them complex and more computational
power consuming as compared to Mobilenet and InceptionV3. Some false classifica tions occur due to inter-class and intra-class similarities
