Drowsiness is one of the main contributing factor in many traffic accidents due to the clear decline in the attention and recognition of danger drivers, diminishing vehicle-handling abilities. A new approach towards automobile safety and security in an autonomous area is primarily expected on the automotive system. To overcome this problem, here is a solution namely the driver drowsiness alert system, which gives an alert by watching each driver’s eye movements in real – time environment. In a process of detecting a person falling asleep, a real time eye detection of the person is acquired. The image processing of an eye through mood detection and adjacent to count of heart rate is analyzed over time to identify drowsiness and fatigue situations, and characteristics indicative of the person falling dormant are determined. To determine openings and closings of the eyes, eye aspect ratio is analyzed to determine the width and height of the eyes, mood discernment analysis through Keras algorithm and heart rate diagnosis manoeuvring heart beat sensor.

The ultimate aim of agriculture or farming in India is not only limited to growing of crops but is also associated with the economic growth of farmers and labours. Rice is one of the staple food crop of our country. Basically in India establishment of rice depends on the availability of moisture, climatic condition, age of the variety, availability of inputs & human labour. Mechanization in agricultural sector is advancing in developing countries like India. Rice is a labour-intensive crop and requires about 80-90 labour days per acre. Timely availability of labour and water for various activities of rice is becoming a problem. Hence to overcome these issues there is a need of mechanization in the field of rice cultivation by using rice transplanter as major tool in this process. There is also need for designing and developing an economical and user-friendly rice transplanter for small scale farmers in order to increase the production as well as the quality of rice. In this paper manual rice planting machine along with their merits and demerits has been discussed by studying various aspects of transplantation related to rice and its field performance which are beneficial to the society and farmers. A rice transplanter is specialized equipment best fitted to transplant rice seedlings on the wet muddy paddy field. This paper is focused on developing a machine which addresses labour problems faced by small scale farmers. The newly developed rice planting machine, can harvest upto two rows of paddy at a time. Outcomes are Reduction in manpower by 80%., Reduction in time by 50%, Reduction in production cost by 50%, Increase in product quality.

For the past few years, neural networks are maturing, and the application domain for the neural network is increasing. Due to the rise in unstructured Image-based data, theres a need for understanding data based upon visual features, not on textual data. Image Captioning in Deep learning is the process to understand different objects in the image, try to build a relation between those objects, and give a sentence that is semantically and syntactically correct. To serve this purpose, Image Captioning uses the combined architecture of Computer Vision and NLP-based Networks as Encoder-Decoder Architecture. In this Survey paper, we discuss the paper[1], which proposed to use Efficient CNN-LSTM based Network using Network Compression. The Network uses CNN-based VGG-16 as encoder and LSTM as decoder network. Network techniques are used such as Quantization and Pruning, to reduce model size up to 73.1% and reduce inference time up to 71.3% and increase BLEU score to 7.7% as compared to uncompressed network.

We propose in this paper a fully automated deep learning model, which learns to classify human actions. Human action recognition is an important application domain in computer vision. Its primary aim is to accurately describe human actions and their interactions from a previously unseen data sequence acquired by sensors. The ability to recognize, understand and predict complex human actions enables the construction of many important applications such as intelligent surveillance systems, human-computer interfaces, health care, security and military applications. Human activity recognition (HAR) is the outcome of a similar motive. Recent times have seen the theory of Human Activity Recognition (HAR) catering to multiple challenging applications built on the increase in ubiquitous, persuasive computing.

Heart rate is the number of heartbeats per minute which is the number of contractions of the ventricles (the lower chambers of the heart). For some human beings it might also be too excessive (tachycardia) or too low (bradycardia) which can cause clinical problems. In the current pandemic situation estimating or monitoring heart rate of a subject with the help of instruments can be risky as it involves physical contact and also one has to visit the clinic which might not be possible all the time. Research focused on non-contact based systems has increased over the past years. Existing systems include those which require contact, some having restrictions on skin tone, and others often involve high costs and complex application of sensors. This paper focuses on real time monitoring of Heart rate of multiple people simultaneously. It is obtained through a real time video using a webcam of laptop/computer. As blood circulation causes facial skin variation, therefore facial video is considered. Signal processing methodssuch as Fast Fourier Transform have been applied on the region extracted after applying colour magnification channels in video recordings. Application also sends a notification via a text message to the specified contact number if the Heart rate is below or above a given range. This algorithm is easy to implement, low cost and simple for real time application. Testing included trials to calculate heart rate of multiple people simultaneously. Once such a trial involved detection of faces of four people and their Heart rate calculation at the same time. Measured value of Heart rate in comparison with the ideal method was within justifiable range. Further, work can be done on environmental conditions which can be very useful in many real time applications.

It takes lots of effort to change your health motivation into an actionable workout schedule. A companion to join in your goals stimulates your motivation as well as acts as a challenging opportunity to grow in the journey. We propose a social networking platform where different users are suggested using User Profile-based recommendation systems using personality analysis. This system helps users to connect with the community or individuals as a companion. With the help of the companion aspect, the daily workout schedule for users and their connections in a network is more simplified, where the possibility of getting demotivated or lost is reduced. A friend recommendation engine is hence needed to provide a good way to diminish this problem as well as satisfy user needs. A recommendation engine facilitates the users by helping them in making an informed decision based on the information they need, like item recommendations based on users’ previous behavior and the information on them collected by the system. Hence, proposing the use of a personality-based friend recommendation framework, which consists of a 3-Layered Artificial Neural Network for friend preference classification and a distance-based sorted subset selection procedure for friend recommendation.
