As the image processing is done with higher level of accuracy with CNN, it is widely used in different real world applications. There are many existing methods that are based on CNN model for object detection.

Saliency guidance is found to be an important optimization to leverage functionality of FRCNN.

A detailed description of the invention
In this considered work a hybrid optimization technique is invented by combining particle swarm with firefly algorithm. This hybrid optimized technique is combined with faster RCNN to obtain high level of rate of accuracy.
First, Faster RCNN is trained with the help of invented weights which are predefined in neural networks. The dataset consists of images and all the images are tuned into even optimized and converted into particles. The PSO further optimizes the weights as the weights are converted as particles. After getting optimized Fireflies are generated. In which the swarm particles are replaced with Fireflies and the search position is updated with respect to intensity of light to obtain the best solution. Finally update Faster RCNN with the weights obtained after applying hybrid optimization technique. Hence the output prediction is calculated and the results are shown. The main aim is to increase the prediction accuracy rate.dimension; n number of nodes are taken as input. The training is performed in the layers and one encoded vector will be consider as output. After the process of training these weights will be
Our object detection system consists of three modules. The first generates category-independent region proposals. These proposals define the set of candidate detections available to our detector. The second module is a large convolutional neural network that extracts a fixed-length feature vector from each region. Finally, third module is we perform classification. The entire process is performed on PASCAL VOC 2007 dataset. The weights updated by using FRCNN is fed to hybrid firefly so that more accurate and better results can be obtained. The hybrid model is combination of particle swarm and firefly algorithm. The hybrid model is discussed in below section. In the faster RCNN anchors which are termed as bounding boxes are present. Here each object is surrounded with a bounding box. The trained data set consists of bounding boxes and which works well for PASCAL VOC dataset. The use of bounding boxes increases the speed of detecting the object and improves in providing high rate of accuracy. The feature extraction performed based on the objects, were all the similar features of the objects present in the bounding boxes are extracted, and regression process is performed in different layers so that major feature vectors are extracted.
Particle Swarm Firefly Algorithm (PSFA),
Both the techniques Swarms and flies are approximately near to each other. Fireflies communicate with each other, try to find the pray and identifies mates using the light pattern which gets flashed. Firefly algorithm is based on some of the ideal traits of fireflies
a. All fireflies are defined as unisex so that the fireflies get attracted irrespective of their sex.
b. Here we compared the relation between attractiveness and brightness which are proportional to each other, thus for any two blinking fireflies, as the proportionality is considered between attractiveness and brightness the distance between the flies increases gradually and the less bright one will move towards the brighter one. When there is no firefly which is brighter than the firefly takes a step towards the other fly.
c. The brightness of a firefly is affected or determined by the landscape of the objective function.
The current invention is characterized by an important contribution to the field of object detection. This contribution is a hybrid bio-inspired method that combines fire fly and particle swarm intelligence. This method is used to optimize weights of FRCNN model in order to improve object detection accuracy. When two fireflies such as x and y are considered, it is possible to have two solutions. The distance between them is computed as given in Eq. 1.
D_xy= v(?(P_x-P_y)?^2 ) (1)
Based on the value of D_xy it is possible to compute attractiveness. Thus x fly’s new position is determined as expressed in Eq. 2 and Eq. 3.
ß= ß_o e^(-?D_xy^2 ) (2)
P_xynew= P_x+ß.rand ?P_xy+ rand (3)
A random number rand is considered to have random solutions produced for x and ß_o. With regard to attractiveness, step wise computation and update is done as in Eq. 4.
?P_xy=(P_y-P_x) (4)
To achieve global best solution P_x^new= P_x if P_x isP_Gbest and P_x^new= P_xGbest^new if P_y isP_Gbest and it complies with the condition P_x^new= P_xy^newwith ?Fit?_best. With particle swarm fire fly method is improved to have optimal weights to FRCNN model. In the process different computations are involved as in Eq. 5 to Eq. 7.
D_xbest= v(?(P_x-P_Gbest)?^2 ) (5)
?P_1xy= P_Gbest-P_worst (6)
?P_2xy=(P_y-P_x+P_D1-P_D2) (7)
In the invented hybrid method fitness function is improved as in Eq. 8.
?P_xy= ?P_1xy if?FF?_x>?FF?_Npop , otherwise ?P_xy= ?P_2xy (8)
Controlling fitness function plays crucial role in the invented method. The controlling process is expressed as in Eq. 9 and Eq. 10.
?FF?_x= (?Fit?_x-?Fit?_Gbest)/?Fit?_Gbest (9)
?FF?_Npop= (?Fit?_Npop-?Fit?_Gbest)/?Fit?_Gbest (10)
In the invention a distribution function is considered and there is uniform distribution for effective swarm search leading to a solution expressed as in Eq. 11.
P_xy^new= P_x+ ßrandn?P_xy+randn (11)
In summary, this invention has two aspects involved. First, it has FRCNN to achieve object detection and the second one is the hybrid bio-inspired method that is made up of firefly and particle swarm methods. The bio-inspired method is designed to optimize performance of FRCNN method. In other words, the weights involved in the FRCNN method are subjected to optimization with the help of bio-inspired method discussed above. Thus the current invention has potential to leverage object detection accuracy.
