… one side of the object more information will be needed. Methods for digital image processing have been examined to be able to answer the question; can an attack against an ordinary door lock be performed by taking photographs of the key that opens the lock, and from the pictures …
The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a …
… band of Landsat 7 in order to improve the spatial resolution of colour images. The images are to be used as texture in visual databases for flight simulators and for this reason it is important that the fusion preserves natural colours. A number of methods for fusing …
… that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator. This topology avoids the use of a multi-bit DAC in the feedback loop ? hence the system does not need …
… of this thesis is to evaluate 7 different search strategies for content-based image retrieval with respect to retrieval effectiveness. The strategies are based on different levels of resolution implemented by the Haar transformation. The result of the study shows an improvement …
en analys av användbarheten med fjärranalys som hjälpmedel till röjningsrådgivning
… project will give answers to questions regarding if an analysis of satellite images can be used to contact and inform landowners of the located areas where precommercial thinning is useful. The whole project is a part of the National Board of Forestrys IT-stake where the …
Information på webben konsumeras idag via en mängd heterogena enheter. Faktorer som nätverksunderlag och skärmupplösning påverkar vilken bild som är lämplig att leverera till klienten, då en bild i sitt originaltillstånd på en tekniskt begränsad enhet tar lång tid att hämta samt …
Managing Huge Datasets
… scanning projects considering digitizing this large scale object at very high resolution. In particular the issue managing and processing huge datasets is described. Finally, the processing of the datasets in the different phases and the resulting 3D model of the Parthenon is …
En studie om mobilt bloggande
… ofthe study that writing blogposts from a smartphone is common and even using images in theblogposts are common. But the technical resolution of pictures from smartphones seemed tointerfere a bit for some of the bloggers in the study.
… have been made to resemble the experiment. In the experiment a Particle Image Velocimeter (PIV) was used as method of measurement. From the experimental report data such as velocity (U), turbulent kinetic energy (k) and standard deviation (URMS) have been obtained and have …
Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?
… dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and …
