This paper concerned with a comparative study and implementation of Interior orientation manually and automatically for KFA1000. In manually method, firstly, we reproduced the image to its reduced size photographically from the original image to be measurable in a mono comparator from 30*30 cm to 23*23 cm which proceeds by measuring of photo coordinates of four pieces of KFA-1000 photo. After c...

We tackle the problem of semi-automatic road tracking in aerial photos. Our solution to this human-computer interaction problem is to provide a learning approach that integrates naturally input from human experts with automatic tracking of roads. More specifically, our system learns an ensemble of road predictors from human inputs and uses them to further track a road, alerting the human expert...

DEFINITION Geographic data are in essence visual multimedia data. To entry those data with keyboards and to print them as tables of data are not very practical actions. For entry, special devices exist (theodolites, lasers, aerial photos, satellite images, etc.) whereas visual layout is currently named cartography or mapping. Visual interfaces have two facets, allowing the user to present their...

This paper will introduce a new approach, mainly based on wavelets transform and mathematical morphology, for the detection of geological faults in satellite and aerial photos. This can be useful for territorial analysis, digital cartography and the use of geographical information systems. The proposed method is fast enough and unsupervised. Different techniques will be compared and some exampl...

Unmanned aerial vehicle-based transmission line inspections produce a large number of photos; significant manpower and time are required to inspect the abnormalities faults in such photos. As such, there has been increasing interest use computer vision algorithms automate detection defects these One most challenging problems this field is identification small pin bolts. In paper, we propose sta...

the tajan river is one of the most important rivers in the north of iran. it seems that in respect of its meander design and pattern, passing over the block's fault and deviations along its way, it's influenced with active neotectonically movements in the region. although being meander in rivers, in the level of a flood water field with very low gradient, isn't unexpected but exi...
