Effect of zooming on texture features of ultrasonic images
Cardiovascular Ultrasound, 2006 Background Unstable carotid plaques on subjective, visual, assessment using B-mode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have standardised B-mode images for ...

Fast Fixed-point Bicubic Interpolation Algorithm on FPGA [PDF]
2019 IEEE Nordic Circuits and Systems Conference (NORCAS): NORCHIP and International Symposium of System-on-Chip (SoC), 2019 We propose a fast fixed-point algorithm for bicubic interpolation on FPGA. Bicubic interpolation algorithms on FPGA are mainly used in image processing systems and based on floating-point calculation. In these systems, calculations are synchronized with the frame rate and reduction of computation time is achieved designing a particular hardware ...

SLIC Based Digital Image Enlargement
, 2018 Low resolution image enhancement is a classical computer vision problem. Selecting the best method to reconstruct an image to a higher resolution with the limited data available in the low-resolution image is quite a challenge.

Impact of eye fundus image preprocessing on key objects segmentation for glaucoma identification
Nonlinear Analysis, 2023 The pathological changes in the eye fundus image, especially around Optic Disc (OD) and Optic Cup (OC) may indicate eye diseases such as glaucoma. Therefore, accurate OD and OC segmentation is essential.

Dynamic programming and bicubic spline interpolation
Journal of Mathematical Analysis and Applications, 1973 AbstractDynamic programming techniques were used to obtain the spline approximation for a function with prescribed values on the knot points along a line. Extending this procedure to two dimensions, the bicubic spline approximation defined over a two-dimensional region is obtained in this paper employing the methods of dynamic programming.

Comparison of spatial downscaling methods of general circulation model results to study climate variability during the Last Glacial Maximum [PDF]
Geoscientific Model Development, 2018 The extent to which climate conditions influenced the spatial distribution of hominin populations in the past is highly debated. General circulation models (GCMs) and archaeological data have been used to address this issue.
