Object detection using SIFT

Surgical teams use instrument counts to prevent leaving unintended objects in patients. This is done manually, but could potentially be done through computer vision software. This paper presents a proof of concept for detecting instruments in the operating room with the Scale Invariant Feature Transform (SIFT). The SIFT algorithm is explored and...

Automatic Cell Viability Determination In Bright-Field Microscope Images

Quantification of non-viable cells in bright-field microscope images allows for an in vitro assessment of the viability of cultured cells. The identification and quantification of non-viable cells in a cell culture is conventionally achieved with viability stains. A disadvantage of viability stains is that they might be invasive and even toxic...

Automating quantity surveying in road construction using UAV Videogrammetry

Due to changing contract forms in road construction, contractors feel the need for accurate and fast quantity measurement methods. UAV Photogrammetry is a potential answer for contractors. Photogrammetric measurement processing should be automated in order to reach its full potential in speed and obtainability. Automatic extraction of reliable...

New point matching algorithm for panoramic reflectance images

Much attention is paid to registration of terrestrial point clouds nowadays. Research is carried out towards improved efficiency and automation of the registration process. The most important part of registration is finding correspondence. The panoramic reflectance images are generated according to the angular coordinates and reflectance value...
