Her finner du Norges fylke og kommunegrenser i GeoJSON format og EPSG:3857 projeksjon. Disse grensene er opprinnelig hentet fra Geonorge, Norges offisielle kart database. Grensekoordinatene fra Geonorge er bare tilgjengelig i UTM 33 projeksjon,...
This video shows an application we are currently working on at the Centre for Innovative Ultrasound Solutions (CIUS). The application is developed using FAST which is integrated with TensorFlow for fast neural network inference.
Apparently, the current NVIDIA drivers (387) which comes with CUDA 9.1 doesn’t compile with the new Linux kernels (4.13+) on Ubuntu. The error report from DKMS will say something like: /var/lib/dkms/nvidia-387/387.26/build/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’:...
This video shows the work in progress on an algorithm for tracking objects captured by a Kinect camera using the FAST framework. FAST now comes with a Kinect module which uses libfreenect2 to stream...
The video shows our first result in the field of deep learning and convolutional neural networks. We designed a neural network which can automatically locate and segment blood vessels in real-time from B-mode ultrasound...
After training a convolutional neural network, one often wants to see what the network has learned. The following python function creates and displays an image with all convolutions of a specific layer as shown...
OpenCL is a great framework, however, AMD’s, NVIDIA’s and Apple’s OpenCL compilers are not. I have worked over 4 years with OpenCL and I have experienced a lot of bugs. Here I present a...
After experimenting with the OpenCL-OpenGL interoperability on AMD GPUs on Ubuntu Linux I got some cryptic error messages from X (see below). This happens both for the AMD APP samples like SimpleGL and my...
Level sets is a mathematical method of evolving contours in Cartesian grids such as images. The method works by considering a function , called the level set function, which has one more dimension than...
The objective of memory mapping files is to increase I/O performance. Memory mapping a file creates a pointer to a segment in virtual memory and the actual loading is performed by the Operating System...
