Where is circular and main scale in sextant?
In a sextant, the circular scale is located on the arc of the instrument and is marked with degrees, allowing for precise angular measurements. The main scale, or the index arm, moves along this circular scale and is typically graduated in minutes for finer adjustments. The combination of these scales enables the user to measure angles between celestial bodies and the horizon accurately. The index mirror and horizon mirror facilitate this measurement by reflecting the observed objects.
How does the microscopes lenses change the position of the image you see?
Microscope lenses use refraction to bend light, which alters the position of the image. The objective lens creates a real, inverted image of the specimen that is then magnified by the eyepiece lens, resulting in a virtual image that appears closer to the viewer. The combination of these lenses allows for high magnification and resolution, making the specimen visible at a scale that reveals fine details. This optical system causes the image to appear larger and shifted relative to the actual position of the specimen.
Why do toilets flush counter clockwise in the northern hemisphere and clockwise in the southern hemisphere?
They don't. That is a myth. The direction that a toilet flushes depends on how the toilet is designed, not what hemisphere it's in. Due to the Coriolis Effect, large scale weather systems and ocean currents rotate in opposite directions in opposite hemispheres, but this effect does not influence things on the scale of toilet bowls.
What is image space and feature space in remote sensing?
The image space is the 2D plane of the image where pixels are located. It represents the spatial space of the image. In other words, when we talk about the location of each pixel in an image, we are talking about image space. On the other hand, feature space is about the radiometric values assigned to each pixel. In case of a grey-scale imagery, only one radiometric value is assigned to each pixel. When we say an image is RGB or multispectral, then each pixel has several radiometric values that are stored in different channels (for instance there are 3 channels of Red, Green and Blue in an RGB image, so for a pixel we have 3 radiometric values). Feature Space is the space of these radiometric values; the radiometric values of each pixel can be plotted in that space and you can create a feature space image. Last example, an RGB image has a 3 dimensional feature space while it still has a 2D image space.
Do tornadoes turn clockwise and counterclockwise?
Both. Most tornadoes turn counterclockwise if in the northern hemisphere and clockwise if in the southern. There is also a small percentage of tornadoes (less than 1%) that turn in the opposite direction from what is normal in their hemisphere.
What is transforme in Photoshop?
Transform command (Edit > Free Transform or Edit > Transform > Scale, Rotate, Scew, Perspective..) allows you to scale image (make smaller or bigger), rotate, make it look in perspective...
What are all the transformations like reflection?
scale, rotate, reflect, Translate(move identical image), Affine Transformation( altering the perspective from which you view the image)
What is the scale factor from an original figure to its image if the image is made using the given method?
* ---- i like bubba stone!! ALOT!!
What is grayscale slicing?
Grayscale slicing involves transforming an image into a binary image by selecting a specific intensity level and then classifying pixels as either foreground or background based on whether their intensity values are above or below the chosen threshold. It is a simple method for segmentation in image processing.
Describe the image of a dilation with a scale factor of 1?
With a scale factor of 1, the image is exactly the same size as the original object.
Why you use gray image in image processing?
gray scale so that we can process our image
How do you find the scale factor of a 2 dimensional figure?
You need information about a pre-image AND and image to work out a scale factor.
How can I make an image zoom in Premiere Pro?
To make an image zoom in Premiere Pro, you can use the "Scale" effect. Simply adjust the scale percentage of the image to make it zoom in.
How do you minimize body image with photo shop?
You can do that from Edit > Content Aware Scale or from Image > Image Size.
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
How can I make an image zoom in on Premiere Pro?
To make an image zoom in on Premiere Pro, you can use the "Scale" effect. Simply select the image in the timeline, go to the Effects Control panel, and adjust the scale percentage to make the image zoom in.
What is the length of image if the scale factor is 8 and the length of figure is 10yds?
Length of image = Length of original*Scale factor = 10*8 = 80 yards.
