The aim of digital subtraction of radiographic images is eliminating the additional shades to increase the resolution and quality of the images. In dentistry, digital subtraction technique can be used for diagnosis of progressive periodontal diseases or evaluation of the amount of jaw bone repair or destruction. In this study, the possibility of digital subtraction with non-expensive techniques...

background and aims. in periapical radiographic technique, the changes will be visible only after considerable deposition or resorption while digital subtraction technique visualizes slight density changes. this study was aimed to compare visualization of density changes in conventional periapical radiographs and digital subtraction technique with or without image enhancement. materials and met...

vehicle detection and classification of vehicles play an important role in decision making for the purpose of traffic control and management.this paper presents novel approach of automating detecting and counting vehicles for traffic monitoring through the usage of background subtraction and morphological operators. We present adaptive background subtraction that is compatible with weather and ...
