What is difference between object space and image space in graphics?
Object space refers to the coordinate system in which an object's vertices and shapes are defined. Image space, on the other hand, refers to the coordinate system in which the final rendered image is created, mapping the object space to the 2D screen space by using projection and transformation matrices. Object space is typically 3D while image space is usually 2D.
What is the difference between an object and an image?
An image is an optical representation of an object.... Object is real... while image is not... i thnk the word imaginary fits for image.... we can take example of our shadow... when light falls on us ( object ) it creates an image (shadow ) in the ground....
What is the object image distance relationship for a flat mirror?
when dealing with a flat mirror object-distance and image-distance should be equal.
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.
Which type of mirrors are used to give an erect enlarged image of an object?
Concave mirrors are used to give an erect and enlarged image of an object. The image formed is virtual, upright, and magnified when the object is placed between the focal point and the mirror's surface.
What is difference between object space and image space in graphics?
Object space refers to the coordinate system in which an object's vertices and shapes are defined. Image space, on the other hand, refers to the coordinate system in which the final rendered image is created, mapping the object space to the 2D screen space by using projection and transformation matrices. Object space is typically 3D while image space is usually 2D.
What is a difference between the mirror image and the object?
A mirror image is a reflection that appears to be reversed left to right, while an object is a physical entity that exists in space. In a mirror image, the image appears as if you were looking at the object's reflection in a mirror.

How can I measure the size of an object from an image?
One way to measure the size of an object from an image is to use a known reference object of a standard size in the same image. By comparing the size of the reference object to the size of the object you want to measure, you can calculate the size of the object in the image.
How does the image distance compare to the object distance?
The image distance is the distance from the lens to where the image is formed, while the object distance is the distance from the lens to the object. In general, for real images, the image distance is different from the object distance. For virtual images, the image distance is negative and the object distance is positive.
What does it mean by OID in X-ray?
It means object to image receptor distance. It's the distance/space between the thing being x rayed and the image receptor (the plate that absorbs the x-rays and forms the image)
Why if you move the object away from the lens the size of the image get smaller?
Moving the object away from the lens increases the object-image distance. According to the thin lens equation, as the object-image distance increases, the image distance increases incrementally more than the object distance. This results in a smaller image size due to the inverse relationship between image size and image distance.
List 5 properties of a virtual image creaed by reflection from a plane mirror?
1. Image is upright 2. Image is virtual 3. Image is of same size as object 4. Image is laterally inverted 5. Distance from object to mirror is equal to the distance from the mirror to the image
What are differentiate object and image?
An object is the actual physical item or entity being discussed, while an image is a representation or likeness of that object, such as a photograph or drawing. The object exists in reality, while the image is a visual depiction of the object.
What is the difference between the object and the image?
An object refers to the physical thing being observed, while an image is a reproduction or representation of the object, typically in a visual form. The object exists in reality, while the image can be a reflection, photograph, drawing, or any other representation of the object.
When was Image Space Incorporated created?
Image Space Incorporated was created in 1992.
A change in the size of an image compared with the size of an object?
The change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.
