My new embedded system based on Rockchip RK3399 is now stepping to next version. Rebuilt all kernel for maximum performance at processing high quality raw images from quad(2×2) MIPI-CSI2 cameras. This new board aquires double channels of dual high speed 5Mpixel MIPI-CSI2 camera in data bus bandwidth in 6Gbps for… Read more »
There maybe many different ways to detect depth of object, but it depends on reflecting signal intense to indentifying the changing of trace. So I am now making a new fast and ineffective algorithm with these steps, gamma, median and applying my own algorithm of edge enhancement, then muxing it’em… Read more »
Applying CLAHE to medical images may going to some shaded on each edge side of object. So I have to correct this problem with fast processing in real time. To make up a prototype correction, I have used same source RAW image, here is a source image in down scaled… Read more »
By using CLAHE algorithm, there’s some problem occurs by object shapes like this: Each edge side of object going too darken by window leveling. It is defecting issue of CLAHE. So I tried to make it corrected with shading correction. Here is source raw image, 14bit gray. First, I need… Read more »
Here I planned to write some lessons to understand what is libtinydicom (Tiny DICOM library) and librawprocessor (RAW Processing library) for most of modern compilers except M$VC – unfortunately I am sorry about supporting M$VC, but I don’t like care about distinct, banishing standard compiler. Ok, let understand what is… Read more »
Prologue High dynamic tone mapping is a kind of graphical thesis to indemnify exposure of whole a image specially such as 256 leveled Red, Green, Blue (+Alpha transparency) formats. But high dynamic calculates all pixel levels as an floating point number with luminance ( in case of RGB, it convert… Read more »
