This paper proposed an automated system that captures an infrared image using Adafruit AMG8833 IR Thermal Camera and record audio via an omnidirectional microphone connected to a sound card and process the data to determine if the swine had experience thermal stress. Temperature together with the frequency and noise intensity of the swine were logged into the system for the data analysis. After the system detected that swine was under thermal stress, the misting and ventilation is activated that reduce the amount of heat the swine had experienced. Two test was conducted for comparison. A controlled setup with the misting and ventilating and an uncontrolled with only the thermal camera and microphone. The data gathered proves that maintaining the pig's temperature at normal levels through the help of an automated sprinkling and ventilating device results to better growth performance.
A counting system is a device used for identifying the number of people present in a crowd. It has a wide variety of uses from fields of statistics, business and social sciences. This study introduces a method of a facial recognition counting system through the use of an unmanned aerial vehicle to capture aerial images of the crowd and the use of MATLAB to process those images to count the number of people present in the crowd. The algorithms used in this paper are Histogram of Oriented Gradients (HOG) and Completed Local Binary Pattern (CLBP) for low density and Gray Level Co-Occurrence Matrix (GLCM) for high density. From the data gathered, the program can classify an object as a head if it can see all of the human facial features like e.g. eyes, nose, mouth, etc. Thus, to obtain the best results in counting people in a crowd using this method, the user must take pictures at an angle and height where the features of the face can be seen, in our case, at 15 degrees and 3.2 meters respectively. But, if applied in an actual field, many people will be facing different directions and some faces will be blocked by other people.
Pattern recognition of concrete surface crack defects is very important in determining stability of structure like building, roads or bridges. Surface crack is one of the subjects in inspection, diagnosis, and maintenance as well as life prediction for the safety of the structures. Traditionally determining defects and cracks on concrete surfaces are done manually by inspection. Moreover, any internal defects on the concrete would require destructive testing for detection. The researchers created an automated surface crack detection for concrete using image processing techniques including Hough transform, LoG weighted, Dilation, Grayscale, Canny Edge Detection and Haar Wavelet Transform. An automatic surface crack detection robot is designed to capture the concrete surface by sectoring method. Surface crack classification was done with the use of Haar trained cascade object detector that uses both positive samples and negative samples which proved that it is possible to effectively identify the surface crack defects.
This research is about translating series of hand gesture to form a word and produce its equivalent sound on how it is read and said in Filipino accent using Support Vector Machine and Mel Frequency Cepstral Coefficient analysis. The concept is to detect Filipino speech input and translate the spoken words to their text form in Filipino. This study is trying to help the Filipino deaf community to impart their thoughts through the use of hand gestures and be able to communicate to people who do not know how to read hand gestures. This also helps literate deaf to simply read the spoken words relayed to them using the Filipino speech to text system.
