Nowadays, people write comments of restaurants and upload related photos to food blogs after visiting there. Developing a mobile application which enables the user to effectively search restaurants from data in these blogs becomes an emerging need. Besides reading the comments, most people will give a glance at food photos of a restaurant and then decide whether to go or what to eat. Therefore, we...
Fault diagnosis based on Principal Component Analysis (PCA) and Discrete Hidden Markov Model (DHMM) for engine are studied. First, the vibration signal feature extraction from the diesel engine is realized by PCA; next, the vibration signal feature extraction algorithm is designed; then DHMM is applied for fault diagnosis; furthermore, a fault classifier based on DHMM with diagnostic databases is...
In this paper, an approach for detecting bridges over water bodies from high resolution SAR images is presented. It consists of two steps: water extraction and bridge detection. A method based on porosity combined with an edge mending algorithm utilizing canny edges is used to extract water bodies firstly. By considering the ubiety of bridges and water bodies, the candidate bridge regions are detected...
