Many traditional NLP steps (lemmatize, POS, NER, stemming...) are skipped when diving to byte level making the process more universal in terms of scope then task specific.
SCENE TEXT RECOGNITION IN MOBILE APPLICATION BY CHARACTER DESCRIPTOR AND STRU...Cheriyan K M
In text detection, our
previously proposed algorithms are applied to obtain text regions
from scene image. First, we design a discriminative character
descriptor by combining several state-of-the-art feature detectors
and descriptors. Second, we model character structure at each
character class by designing stroke configuration maps.

Participants will learn about different image compression techniques, such as lossless and lossy compression, as well as the popular image file formats, including JPEG, PNG, and GIF. We will also cover topics related to image quality assessment, including subjective and objective methods of measuring image quality. By the end of the presentation, participants will have a solid understanding of digital image coding and compression, as well as the factors that influence image quality.
Text detection and recognition from natural sceneshemanthmcqueen
Text characters in natural scenes and surroundings provide us with valuable information about the place and even provide us with some legal/important information. Hence it’s very important for us to detect such text and recognise them which helps a lot. But , it’s not really easy to recognize those text information because of the diverse backgrounds and fonts used for the text. In this paper, a method is proposed to extract the text information from the surroundings. First, a character descriptor is designed with existing standard detectors and descriptors. Then, character structure is modeled at each character class by designing stroke configuration maps.In natural scenes , the text part is generally found on nearby sign boards and other objects. The extraction of such text is difficult because of noisy backgrounds and diverse fonts and text sizes. But many applications have been proven to be efficient in extraction of text from surroundings. For this , the method of text extraction is divided into two processes;
Text detection
Text recognition
This includes different line drawing algorithms,circle,ellipse generating algorithms, filled area primitives,flood fill ,boundary fill algorithms,raster scan fill approaches.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
2. The way a primitive is to be displayed is referred to as an
Attribute Parameter.
Some attribute parameters include color ,size etc.
Different ways to incorporate attribute changes :
Extend the parameter list associated with each primitive
Maintain a system list of current attribute values and use
separate functions to set attributes.
4. Type :
Solid
Dotted – very short dash with spacing equal to or greater than dash itself
Dashed – displayed by generating an inter dash spacing
Dash Dotted –combination of the earlier two
To set line type attribute in PHIGS Application,
setLineType(lt) can be used. Lt can be -1,2,3,4
5. Raster Line algorithms display line attributes by plotting pixel spans.
Pixel count for the span and inter span length and inter span spacing can be
specified using the mask .
Ex. 111100011110001111
Plotting dashes with fixed number of pixels result in unequal-length dashes for
different line orientations. Horizontal line looks small when compared to a
vertical line.
For dash lines to remain constant, we should adjust the pix span el count for the
solid span and inter space span according to the slope of the line.
6. Specify in pixels and proportion of a standard line width.
Thicker line can be produced by.
. Adding extra pixel vertically when |m| < 1
. Adding extra pixel horizontally when |m| > 1
We can set the width of a line using setLineWidthScaleFactor(lw);
Where lw is assigned a positive number.
7. Issues:
Line have different thickness on the slope
Problem with
. End of the line (Use Line Caps)
. Joining the two lines (polygon)
8.
9.
10. The selected “pen” or “brush” determine the way a line will be drawn.
Pens and brushes have size, shape, color and pattern attribute.
Pixel mask is applied in both of them.
11. A polyline procedure displays a line in current color by setting this color value in
the frame buffer at pixel locations along the line path using the set Pixel function.
setPolyLineColorIndex(lc)
A line drawn with background color in invisible.
12. Similar to line : type + width
Thicker curves can be produced by:
1. Plotting additional pixel
2. Filling the space between two concentric circles.
3. Using thicker pen or brush
13.
14.
15. Color
General Purpose raster scan systems provide a variety of colors while
random scan monitors provide very few.
Colors are represented by colors codes which are positive integers.
Color information is stored in frame buffer or in separate table and use
pixel values as index to the color table.
Two ways to store color information :
1. Direct
2. Indirect
16.
17.
18. Apply for monitor that have no color
Shades of grey (white->light grey->dark grey->black)
Color code mapped onto grayscale codes
2 bits can give 4 level of grayscale
8 bits per pixel will allow 256 combination
Dividing the actual code with 256 will give range of 0 and 1
Ex:
Color code in color display is 118
To map to nearest grayscale then
118/256 = 0.45
light gray
19. Option for filling a defined region is whether solid , pattern and colors.
Fill Styles
Three basic fill styles are:
1. Hollow with color border
2. Solid
3. Patterened
20.
21. A basic fill style can be assigned in a PHIGS program using the following
function:
setInteriorStyle(fs),
Where fs c an be hollow,s olid,or pattern .
Another value for Fill Style is Hatch, which is used to fill an area with
selected hatching patterns.2 types :
Diagonal Hatch Fill and Diagonal Cross Hatch Fill.
22. The color for a solid interior or for a hollow area outline is chosen with :
setInteriorColorIndex(fc) where fc is the desired color code.
Other fill options include specifications for the edge type, edge width edge
color of a region.
23. We select fill patterns with
setInteriorStyleIndex(pi), where pi specifies a table position
For fill style pattern, tables entries can be created on individual output
devices with :
setPatternRepresentation (ws,pi,nx,ny,cp)
Where,
pi is pattern index number,
ws is the workstation code,
Cp is the 2d array of color codes with nx columns and ny rows.
