Image processing techniques applied for pitting corrosion analysiseSAT Journals
Abstract
In order to study the behavior of the early stage of pitting corrosion, an image analysis based on discrete wavelet packet transform
and fractals was used. Image feature parameters were extracted and analyzed to characterize the pitting corrosion development with
test time. It was found that the feature parameters: Shannon entropy, energy, fractal dimension and intercept increased with the test
time. Therefore the image processing techniques were promising and effective tools to analyze and detect the pitting corrosion.
Keywords: corrosion, pitting corrosion, surface topography, surface analysis, carbon steel, tap water

Unsupervised Building Extraction from High Resolution Satellite Images Irresp...CSCJournals
Extraction of geospatial data from the photogrammetric sensing images becomes more and more important with the advances in the technology. Today Geographic Information Systems are used in a large variety of applications in engineering, city planning and social sciences. Geospatial data like roads, buildings and rivers are the most critical feeds of a GIS database. However, extracting buildings is one of the most complex and challenging tasks as there exist a lot of inhomogeneity due to varying hierarchy. The variety of the type of buildings and also the shapes of rooftops are very inconstant. Also in some areas, the buildings are placed irregularly or too close to each other. For these reasons, even by using high resolution IKONOS and QuickBird satellite imagery the quality percentage of building extraction is very less. This paper proposes a solution to the problem of automatic and unsupervised extraction of building features irrespective of rooftop structures in multispectral satellite images. The algorithm instead of detecting the region of interest, eliminates areas other than the region of interest which extract the rooftops completely irrespective of their shapes. Extensive tests indicate that the methodology performs well to extract buildings in complex environments.

Detection of Bridges using Different Types of High Resolution Satellite Imagesidescitation
Automatic detection of geographical objects such as roads, buildings and bridges
from remote sensing imagery is a very meaningful but difficult work. Bridges over water is
a typical geographical object and its automatic detection is of great significance for many
applications. Finding Region Of Interest (ROI) having water areas alone is the most crucial
task in bridge detection. This can be done with image processing / soft computing methods
using images in spatial domain or with Normalized Differential Water Index (NDWI) using
images in spectral domain. We have developed an efficient algorithm for bridge detection
where the ROI segmentation is done using both methods. Exact locations of bridges are
obtained by knowledge models and spatial resolution of the image. These knowledge models
are applied in the algorithm in such a way that the thresholds are automatically fixed
depending on the quality of the image. Using the algorithm any type of bridges are extracted
irrespective of their inclination and shape.
Comparison of specific segmentation methods used for copy move detection IJECEIAES
In this digital age, the widespread use of digital images and the availability of image editors have made the credibility of images controversial. To confirm the credibility of digital images many image forgery detection types are arises, copy-move forgery is consisting of transforming any image by duplicating a part of the image, to add or hide existing objects. Several methods have been proposed in the literature to detect copy-move forgery, these methods use the key point-based and block-based to find the duplicated areas. However, the key point-based and block-based have a drawback of the ability to handle the smooth region. In addition, image segmentation plays a vital role in changing the representation of the image in a meaningful form for analysis. Hence, we execute a comparison study for segmentation based on two clustering algorithms (i.e., k-means and super pixel segmentation with density-based spatial clustering of applications with noise (DBSCAN)), the paper compares methods in term of the accuracy of detecting the forgery regions of digital images. K-means shows better performance compared with DBSCAN and with other techniques in the literature.
A brief information about the SCOP protein database used in bioinformatics.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

2. Why 250 m was used between the points during the construction of faulted surface?(page 31)
3. What is the general theoretical background of densification?
4. There are no any distance scale on the maps, figures.
5. Why 200m was used as a distance criteria during the S-grid creation process? (page 36)
6. The intrusion seems to be situating on the surface (page 40 fig 3.21)
7. Although DSI is explained a bit, there are no general explanation which one is better in a given geological
settings.

8. Which ore body model is more plausible or realistic (Kriging or DSI based)?
9. Is there any scientific outline about the refilling velocity of hot water between the wells? (there will be a
bulge and a depression in the waterf level.)

Q1
Explanation for mark 4
1. The used interpolation algorithms are not explained: page 43:
DSI or Discrete smooth interpolation is a point estimator whose criteria is to minimise the local curvature (second
derivative) between the data points values (coordinate, grades, properties) to be interpolated. The DSI interpolator
reduces the fitting error between the sampled point (called controlling object) and the data model while keeping as
objective to be as smooth as possible (GOCAD help). The advantage of this method is that it is an exact estimator and
numerically stable.
Kriging is an optimization technique based on regression against observed z values of surrounding data points in a
neighborhood, weighted according to spatial covariance values (Bohling, 2005). In other words, kriging is a point
estimator with a principle of minimizing the estimation variances (Matheron, 1962; Journel and Huijbregts 1978).
Kriging in GOCAD calculates both an estimation (estimation of the value Z) and an error variance (estimate of the
error). Kriging requires a variogram calculated on the dataset. To do the kriging, the calculated empirical variogram
has to be replaced with a “synthetic” fitted theoretical variogram.
2. Which result is closer to the reality: page 47
One of the advantage of kriging is that it considers the spatial variability of the elements by using variogram
→ kriging
3. Why would be fruitful to choose DSI or Kriging? Page 47

19. Questions from the reviewer: Dr. Szentpéteri Krisztián
My questions to the author:
1) Based on the geological modelling exercise, where would the author target; 1) exploration drilling that would the
most potentially expand the resources and 2) infill drilling that would the most potentially enhance the quality and
confidence of the resource modelling?
2) Based on the variogram analysis how many ore types can the author recognize, what they are and where they are
located in the 3D modelling space?
3) Has the author ever performed the following exercise: looking at only the assay data, without anything else (no
sections, no surface, no geophysics) purely the points hanging in the empty 3D space?
4) What does the author think; what will be the most useful geological data for modelling Recsk Deep skarn
mineralization and why?

2) Based on the variogram analysis how many ore types can the author recognize, what
they are and where they are located in the 3D modelling space?
At least 3 structures can be distinguished based on sill/nugget of horizontal variograms:
- 100 m: Au,
- 350 m: Cu, Zn, Mo
- ~700 m: Pb, Ag
