vimage | A simplistic image viewer for Windows , inspired by vjpeg | Computer Vision library

I find this answer, and I want to use pyvips to resize images. In the mentioned answer and the official documentation image resized by scale. However, I want to resize the image to a specific height and width. Is there any way to achieve this with pyvips?

I am using the pyvips library which has a special object for images, these objects have the 3 bands corresponding to HSV (or other) colour space components. The problem is that, after filtering one of the HSV components, it is not allowed to assign it again to the ogirinal image. On this code you can see what is written and the error.

I have images in my mongo atlas DB and I need to retrieve them from the server and display them dynamically to the client using React.

How do I get the image data from mongo DB using mongoose and display that image dynamically to the client side. (Note: I want to save the image and load it dynamically in another component.

The problem is the constructor function of getting the image, that is the code on the very top (exports.getImagePost) and it is also in the react client where the http is passing the id for the preview image (const GetPostVerse = ({ match }) => {). Also I have tried to upload it to storage with NPM multer and it doesn't store the image in DB, it just shows it on the client end. Note: the image is saved properly in the DB

I have attempted to write a constructer that will be my function to get the image by id from the DB and render it on the client side, and I am not seeing the image:

Here is the code to get the image from server

I am doing some realtime image analysis on a live videostream. I am using vImage to calculate histograms and vDSP for some further processing. I have Objective-C code that has been working well over the years. I am now about to convert it to Swift. And while it works it is too slow. I have found that the main problem is converting the vImage histogram, which is UInt (vImagePixelCount), to Float that vDSP can handle. In Objective-C I am using vDSP to do the conversion:

I try to make some histogram calculations using vImage buffers in Accelerate framework and I supply camera image as UIimage converted from CVpixelbuffer. Algorithm works with no error however processed camera image data on the screen is very slow. I read some info in Apple documentation about freeing the buffers when task is completed. I wrote two lines of code after grab the buffer data. However nothing changes. Please see attached screenshot of buffers data after they are freed.SourceBuffer and histogramSourceBuffer are seems not freed. I don't know how a free buffer has to be seen in debugger but mine are shown with height, width and data info. Any recommendation how to free the buffer and how can I ensure it is freed. Many thanks indeed

I try to generate a Gatsby blog starter using following command:

Hi I am doing a small model which predicts fruits. I have a function which runs a series of predfor various images and they output the prediction as shown below.

[[0. 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]]

I know the output is not an array, however I would like to know if there is a possible way to check the values at certain positions. For example, if it was an array, i would have done:

I am getting an error:

The cast to value type 'System.Int32' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.

when there is no record in db.recordImages. I thought with a join (left) and DefaultIfEmpty() it would solve this. When there is a record all works fine. Any ideas?
