The merged image includes the information of the original images and improves the reliability and intelligibility for object detection and target recognition. The most widespread methods for image fusion are wavelet transform based methods. However, the facts that the original pixel values of input images are not preserved in the fused image and different multi-scale image fusion schemes will lead to different results cause that the wavelet methods present a limited quality performance compared with a cut and pasted fusion reference model. In this paper, a new multi-focus image fusion approach is proposed based on non-negative matrix factorization (NAIF). The cut and pasted fusion scheme is adopted in the new fusion approach. Cut the source images into small-size blocks, factorize the corresponding image blocks using NAIF, pick out the sharpest blocks according the NAIF coefficient, and combine them as an in-focus image. The experiment results show that the proposed approach outperforms the wavelet based fusion methods, both in visual effect and objective evaluation criteria.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131690992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It only requires three views from the newly designed planar calibration pattern, which is a square tessellated model plane with the black-and-white alternate square grids, then all the five intrinsic parameters can be recovered linearly. Our calibration method needs; neither any geometric measurements on the model plane, nor any matching information between the model plane and the image plane, and avoids the errors caused by the pick-up of irregular geometry feature from the image. It greatly decreases the system setup costs and simplifies image feature extraction works. Hence the calibration process is easily performed for the user. Experimental results on simulated data and real data show the feasibility of the proposed technique.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115464372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result of an oceanic experimentation presents that the algorithm does improve the performance in the oceanic reverberation background. Especially, in the processed beam image, the target is very distinct. Comparing with single traditional anti-reverberation method, the algorithm fully utilizes the temporal and spatial difference between detection signal and reverberation to optimize the localization and detection.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121396450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A low-cost microcontroller is used to control a hydraulic actuator to repeatedly lift and drop a standard free-falling weight that strikes a pipe (sampler) which is pushed deeper into the ground with each impact. The depth of the sampler pipe and position of the hydraulic cylinder are monitored and the number of drops, soil penetration depth and other test information are recorded in a database for future analysis. This device, known as the \"automated trip hammer\" (ATH), allows the automation and faster completion of a typically labour-intensive and slow testing process that can introduce human error and the risk of serious injuries.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131692106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes a mobile robot system designed for simultaneous localization and mapping (SLAM) for an autonomous mobile robot in an indoor environment. Due to variant sensor modeling for laser range finder and CCD camera, weighted least square fitting and Canny operator are used to extract certain two-dimensional environmental features and vertical edges respectively. Using Kalman filtering (KF) to localization and grid map building simultaneously are also presented. When implemented on a Zixing mobile robot produced by Harbin Institute of Technology (Weihai), the localization technique correctly localized the robot while exploring and mapping.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"63 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113962384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
