Thresholding.ppt
Thresholding is a technique for image segmentation where each pixel is classified as either foreground or background based on a threshold value. It can be used for images with light objects and a dark background by selecting a threshold that separates the intensities. More generally, multilevel thresholding can classify pixels into object classes or background based on multiple threshold values. Thresholding views segmentation as a test against a threshold function of pixel location and intensity. Global thresholding uses a single threshold across the image while adaptive thresholding uses local thresholds.

This document presents a new model for simultaneous sharpening and smoothing of color images based on graph theory. The model represents each pixel as a node in a weighted graph based on its color similarity to neighboring pixels. Smoothing is applied to pixels within the same connected component as the central pixel, while sharpening is applied to pixels in different components. Experimental results show the method can enhance details while removing noise. Future work includes optimizing parameters, measuring performance, and combining sharpening and smoothing parameters.

The goal is to add value through efficient transformations. Operations can be categorized as manufacturing or service-based. Manufacturing operations produce tangible goods while service operations provide intangible activities and require customer participation. Operations management is one of the three primary business functions along with finance and marketing, and it plays a significant role in an organization's success.
Fingerprint Recognition Technique(PPT)
This document summarizes a student project on fingerprint recognition. The project involved implementing a fingerprint recognition algorithm using minutia extraction and matching. The algorithm included preprocessing stages like histogram equalization, Fourier enhancement, binarization, and thinning. Minutiae were then extracted and matched to determine if two fingerprints came from the same finger. The results showed the algorithm could accurately match fingerprints from the same finger but determine fingerprints from different fingers did not match.

Here are the key steps to convert a color image to a binary image in LabVIEW:
1. Read in the color image using the Read PNG or Read JPEG VI. This will return an image structure.
2. Use the Color To Gray VI to convert the color image to grayscale. This removes the color information and leaves only the luminance.
3. Apply a threshold to convert the grayscale image to binary. Use the Threshold VI and choose an appropriate threshold value (usually 128 for 8-bit images).
4. The output of the Threshold VI will be a binary image, where pixels above the threshold are white (255) and pixels below are black (0).
5. You can now process the binary

Spatial domain methods operate directly on pixel values using point processing or neighborhood filtering. Key spatial techniques include contrast stretching, thresholding, and histogram equalization. Frequency domain methods modify an image's Fourier transform. Common transformations include logarithmic, power-law, and piecewise linear functions, which can increase contrast or highlight certain grayscale ranges. Proper enhancement improves an image's features for desired applications.

While it may not provide perfectly accurate reasoning, it can provide acceptable reasoning and help deal with uncertainty in engineering problems.
Satellites launching procedure and vechicles
Satellites are launched into orbit using launch vehicles, which can be either expendable or reusable. Expendable vehicles are designed for single use and are not recovered after launch, while reusable vehicles like the Space Shuttle can launch payloads into space more than once by recovering components like the main engines and solid rocket boosters. To reach higher orbits over 200km, satellites are first launched into a lower transfer orbit using rockets before using onboard motors to circularize into the final destination orbit. Launch procedures take into account factors like the desired orbit, weather conditions, and precise timing.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
