However if you really want to use imread then you have to tell cv image the type of pixel in opencv s mat object which is usually bgr pixel.

Use opencv to convert img to mat. You do not need to think about memory management with opencv s c interface. I still notice frame corruption. The use of encoding is slightly more complicated in this case. I have tried using cudamalloc during program initialization cudafree after the while loop.

Hi the dnn imagenet ex cpp example in line 141 load image as a matrix rgb pixel. The ros image message must always have the same number of channels and pixel depth as the cv mat however the special commonly used image formats above bgr8 rgb8 etc will insert. The assignment operator and the copy constructor only copies the header. But it has more applications for convolution operation zero padding etc.

You can use dlib load image to read an image without open cv. Hello i have been give a task to convert multiple jpg image files to matlab mat files each having 5 fields. Anyone who knows how to deal with the p. I want to read the image by opencv and i faced the problem to transform the type of cv mat to matrix rgb pixel.

How do we do the correct conversion from opencv mat to the format that detectnet requires. The underlying matrix of an image may be copied using the cv mat clone and cv mat copyto functions. But when the matlab function load filename mat was used it produced a mat file with 5 field names. I tried using the import data tab but was only given one field.

It does as before refer to the cv mat however cv2 to imgmsg does not do any conversions for you use cvtcolor and convertscale instead. Making borders for images padding if you want to create a border around the image something like a photo frame you can use cv copymakeborder function.
