Object color space is highly structured due to optical constraints (radiant power non-negative, reflectance factors between zero and unity) ecological context (daylight illuminant). In this setting trichromacy induces a natural geometry through unique spectral tripartition. Different from null-context colorimetry, one gains two desirable relations: The colorimetric coordinates are coarse-graine...

We present Johnson UBV , and Kron-Cousins I photometry for about 60,000 stars in a region of 44 × 33 arcmin2 centered on the Galactic globular cluster (GGC) NGC 2808. The central r < 100 arcsec region has been mapped also in the F218W, F439W, and F555W bands with the HST WFPC2 camera. Overall, we cover a field which extends from the center to about 1.7 tidal radii. Photometric calibration has b...

Preface In the past nine months, I carried out my the final year project of KTH international master's in SoC (System-on-Chip) at NXP Semiconductors Research (NXP), the Netherlands. Thanks to my supervisors, Prof. Axel Jantsch in KTH and Senior Scientist Tomas Henriksson in NXP. Also thanks to Pieter van der Wolf and Bram Riemens in NXP. During my internship they gave me a lot of help on the te...

We present RGB-D-Fusion, a multi-modal conditional denoising diffusion probabilistic model to generate high resolution depth maps from low-resolution monocular RGB images of humanoid subjects. RGB-D-Fusion first generates map using an image conditioned and then upsamples the second on RGB-D image. further introduce novel augmentation technique, noise augmentation, increase robustness our super-...

Traditional indoor laser scanning trolley/backpacks with multi-laser scanner, panorama cameras, and an inertial measurement unit (IMU) installed are a popular solution to the 3D indoor mapping problem. However, the cost of those mapping suits is quite expensive, and can hardly be replicated by consumer electronic components. The consumer RGB-Depth (RGB-D) camera (e.g., Kinect V2) is a low-cost ...

We present observational estimates of ∆V Bump HB in a sample of 28 Galactic Globular Clusters (GGCs) observed by HST. The photometric accuracy and the sizable number of stars measured in each cluster allowed us to single out the RGB Bump both in metal-poor and in metal-rich GGCs. Empirical values are compared with homogeneous theoretical predictions which account for both H and He burning phase...

The distance to NGC 5128, the central galaxy of the Centaurus group and the nearest giant elliptical to us, has been determined using two independent distance indicators: the Mira period-luminosity (PL) relation and the luminosity of the tip of the red giant branch (RGB). The data were taken at two different locations in the halo of NGC 5128 with the ISAAC near-IR array on ESO VLT. From more th...

We present V and I photometry of a 9.4 ′ × 9.4 ′ field centered on the dwarf spheroidal galaxy Leo I. The I magnitude of the tip of the Red Giant Branch is robustly estimated from two different datasets (I T RGB = 17.97 +0.05 −0.03). From this estimate, adopting [M/H] ≃ −1.2 from the comparison of RGB stars with Galactic templates, we obtain a distance modulus (m − M) 0 = 22.02 ± 0.13, correspo...

The main problem in colour management in prepress department is lack of availability of literature on colour management and knowledge gap between prepress department and press department. So a digital test from has been created by Adobe Photoshop to analyse the ICC profile and to create a new profile and this analysed data is used to study about various grey scale of RGB and CMYK images. That h...
