Abstract

Feature extraction techniques are applied to obtain features that will be useful in classifying and recognizing images. Feature extraction techniques are very helpful in various image processing applications. Many studies show the effectiveness of feature extraction before classification. There is also research showing that a feature extraction method may be good for certain classification approaches but may also be preferable. The impact of the sample and its size can also determine the results of the application of feature extraction techniques in the classification process. In this study, the author aims to prove the effectiveness of the application of the HOG feature extraction technique on the classification with the SVM method on flower images. The experiment was carried out on two groups of images, where the first group was image classes with relatively uniform colors and shapes, both in shape and color. and the second group is image classes with relatively different colors and shapes in the same class. The results showed that image datasets with relatively uniform colors and shapes do not require the application of any feature extraction to produce high accuracy. For classification by performing feature extraction in this study it gives different results for the two interest groups.

Abstract

AbstractThe growth of plants requires watering the plants so monitoring is necessary. Monitoring is carried out for the process of watering plants running optimally according to plant needs based on soil moisture and room temperature. Soil moisture explains that it settles between the soil pores, this is also due to evaporation of the soil surface, transpiration and infiltration. The purpose of this research is to do watering using a jet irrigation system so that it is done automatically in watering the soil according to the humidity and temperature required for the plants. The important factor of soil moisture is influenced by factors including the quality of the soil used as agricultural land, namely the life of the biological elements contained in the soil including hosts, pathogens, and also various other microorganisms, greatly affecting soil moisture. Determine the amount of water flow that flows from the water source to the soil element in order to get the appropriate level of humidity. In this study, the authors used cayenne pepper and red chili as the object of research, where these plants can grow at an optimal temperature of 24˚C – 28˚C, so it is necessary to monitor temperature and soil humidity using Arduino sensors to create a jet irrigation system. Keywords : Monitoring; Arduino Sensors; Water discharge; Radiant irrigation system
